Troubleshooting Guide to Troubleshooting the Printer Introduction This chapter will guide you through the relevant steps to take when troubleshooting the printer. Troubleshooting System Error Codes Chapter 2 - System Error Codes contains a list of system error codes and their respective descriptions and recommended corrective actions. Only try one recommended action at a time and check if the error code has disappeared.
Troubleshooting Performing a Service Test on a Failed Assembly If possible, always perform a Service Test on the component/ assembly that you are about to replace, just to make sure that is the component/assembly that has failed. NOTE If the test on that component/assembly passes, you should NOT replace it. For information on the Service Tests and how to use them see Chapter 4 - Service Tests and Utilities.
Troubleshooting Front-Panel LEDs Flash Briefly at Power ON & Nothing Else Happens The Power Supply detects a Short and shuts down the Power. 1 The Hard Disk Drive or the Network Card could be faulty. Troubleshoot the problem as follows: a If the Printer has a Hard Disk Drive and/or a Network card installed, switch the Printer OFF from the back of the Printer, and remove them both. b Switch the Printer ON again.
Troubleshooting The Printer does not Power ON 1 Check that the power cord is connected correctly to the Printer and to the Power Socket. 2 Check that the Firmware DIMM is installed correctly in the correct slot (the first slot from the right) at the back of the Printer. 3 Check that the Power Switch on the BACK of the Printer is in the ON position. 4 Check that the Front-Panel Cable is correctly connected to the Electronics Module. Also make sure that the Front-Panel cable is not damaged.
Troubleshooting The Printer Continuously Rejects Printheads 1 Clean the flex contacts on the Printhead and in the Carriage Assembly using the Carriage Interconnect Wiper (Refer to Chapter 3) and try again. 2 If ALL the Printheads are rejected (the status message on the Front Panel does NOT show "OK" for all the Printheads) then perform the Electronic Systems Test ⇒ Page 4-5. Cover Sensors are not Working 1 Check if the faulty sensor is installed correctly.
Troubleshooting Troubleshooting Media Jams/Printhead Crashes NOTE If using HP Coated Media when problem occurred, please also refer to Page 1-10, Printhead Crashes/Smears on High Density Prints Using Coated Media. The failure modes "media jam" and "head crash" are grouped together because in many cases a media jam causes the media to lift up into the carriage path and cause a head crash, thus causing many media jam failures to be reported as head crashes.
Troubleshooting problem as explained as follows. WARNING In each case, make sure that you power OFF the printer before attempting any procedures to resolve the problem. Printhead Cleaner Path 1 Open the right door of the printer and check for any visible obstacles restricting the movement of the Service Station. Manually move the Service Station, checking for smooth and free movement. Paper Path 1 Open the Window and check for any visible obstacles restricting the movement of the Drive Roller.
Troubleshooting Problems with the Vacuum Fan If you have problems loading either Roll or Sheet Media, then there could be a problem with the Vacuum Fan. To verify if there really is a problem with the Vacuum Fan, try the following: 1 With the Printer ON, open the Window of the Printer and place a sheet of HP High Gloss Photo Paper (must be D-Size), aligned with the blue lines on the Center Platen.
Troubleshooting Printhead Crashes/Smears on High Density Prints Using Coated Media High density prints can cause cockle mainly on HP Coated Media. This causes two main problems: 1. Cockling in the borders - Because the printer places too much ink on the Coated Media, the borders of the print become raised, causing the Printhead to crash against the media. To solve the problem, try the following: n n Check in the Front Panel if Ink Limiting is ON or OFF. If Ink Limiting is OFF, turn it ON.
Troubleshooting HP-GL/2 color differences in different HP DesignJet Printers Color differences between one image printed on the HP DesignJet 1000 Series and the rest of the DesignJet platforms are due to the different chemistry of the 1000 series inks compared with the rest of the inks for other printers. This color variability among different HP DesignJet Series Printers has been always present.
Troubleshooting Banding at variable extreme environmental conditions Since the Accuracy Calibration has been done at normal environmental conditions, printing in extreme environmental conditions will cause banding because the advance of the Drive Roller does not correspond to the same conditions that the calibration was done in.
Troubleshooting Lower image gloss directly after printing on HP High Gloss Photo Paper Lower gloss appearance of the print when the media is drying which gradually disappears to get the final gloss level (between 10 and 60 minutes depending on the ink density). Try the following: n Wait at least 60 minutes to achieve the high gloss appearance.
Troubleshooting Solving Media-Handling Problems The Front Panel Keeps Indicating that Media Is Misaligned or Incorrectly Positioned Roll media n n WARNING Ensure that the paper is wrapped tightly on the roll. This is a very important step to remember because if this is not done, the media may be loaded at an angle, causing the media to be rejected. n n Sheet media n n n n n 1-14 The roll may be loaded the wrong way. The paper should load over the roll toward you.

Print Quality How to Use the Print Quality Test What is the Print Quality Test? The Printer contains an internal Print Quality Test which helps you to diagnose the possible source of any print quality defects. The Print Quality Test is divided into three parts: a Nozzle print test, designed to check if the printhead nozzles print correctly. b Color alignment test, designed to check any color-to-color misalignment the printer may have.
Print Quality Utilities 2 Select Print Quality from the Utilities/Test Prints menu, then press Enter to print the test.
Print Quality Nozzle Print Test The nozzle print test is located on the Print Quality Test in the top section. In this test the 512 nozzles that each printhead uses to print with are tested. This is what you would see if there are nozzles not printing correctly: Missing Lines Partial Printing Missing Lines Misdirected Lines Unequal Spacing C6074282 1 In the top pattern of the Print Quality Test, there is a series of stepped diagonal lines.
Print Quality How to fix the Nozzle Defects NOTE If your printer has nozzle defects, it does not mean that you will not get perfect print quality results. The printer has automatic procedures to hide many nozzle defects. This type of problem affects mostly Normal and Draft modes. 1 Go to the Printer submenu and press Enter.

Print Quality Overall Print Quality Test in BEST mode Blue, Green, Red, Black, Yellow, Magenta, Cyan Test This test pattern checks performance for banding in Best mode only for the media you are using. 3 C6074279 What is Banding? Banding is when you see repetitive horizontal bands within your printed image (these may appear as light or dark bands). The test pattern is printed with four primary colors; black, cyan, magenta and yellow.
Print Quality Solving the Banding Problem There main causes of banding: n Printhead problems (see below). n Use of Non-HP media n Incorrect media type selected in the front panel. n Media advance problems. Banding Caused by Printhead Problems In this case you will see banding in only a few colors.
Print Quality 2 The light or dark horizontal lines could also be caused by permanently damaged printheads. The possible combinations with this problem are: n Banding in cyan, blue and green columns only, but more evident in cyan. This means that the cyan printhead could be permanently damaged. n Banding in magenta, red and blue columns only, but more evident in magenta. This means that the magenta printhead could be permanently damaged.
Print Quality Banding in all of the colors 1 Make sure that the media selection made in the front panel is the same as the media that you have loaded. Utilities Calibrations Accuracy Recalibrate 2 It is possible that the banding was caused because the customer was using non-HP media. If the customer still wants to use non-HP media, recalibrate the paper accuracy by performing the accuracy calibration. Performing this will overwrite the default setting for only the paper that you have selected.

Print Quality 11 When you look at the image you have printed there is banding on the image, but only in a few colors, similar to the example shown below. 3 C6074280 a The possible combinations with this problem are: n n n n Banding in cyan, blue and green columns only, but more evident in cyan. This means that the cyan printhead could be permanently damaged. Banding in magenta, red and blue columns only, but more evident in magenta. This means that the magenta printhead could be permanently damaged.
Print Quality No Printing Defects Found in the Print Quality Test If all the test patterns from the Print Quality Test are correct and you still experience print quality problems, here are some of the more likely causes to check: n The print mode used in your printer is not right for the image you are printing (this is defined by the printer’s front-panel menu selections) n Non-HP driver n The RIP (If you are using one) n The software applications you are using.
Print Quality Solving Color Accuracy problems These are two areas you should review when troubleshooting a color accuracy problem: Configuration (PostScript option only) Check that you are using the correct driver setting and CRD information for the software. Check which ink emulation mode has been selected in the front panel. Media Make sure that the media loaded is genuine HP media and that the correct media type has been selected on the front panel and in the driver.
Print Quality Color Accuracy Configuration The configurations of the printer, the driver, and the software RIPs define how ink is applied to each type of media. Use the information in the following table to configure the printer and software for best color accuracy.
Print Quality Media Always make sure that the customer is using the appropriate media for the required image and that it is consistent with the software application being used. To ensure color accuracy and print-quality performance of the printer, only media types that have been certified for the printer should be used. Use of non-HP media or HP media not certified for the printer may significantly reduce the color and print quality of the required images.

Functional Overview Introduction This Chapter contains a simplified description of the HP DesignJet 1050C/1055CM Printer circuits and mechanical functions. Mechanical and printed Circuit Assembly (PCA) overviews present a functional description of how the Printer operates. HP DesignJet 1050C Printer The HP DesignJet 1050C will have a network interface, 16 MB of memory but will NOT include the Hard Disk Drive.
Functional Overview n n sensor. Service station: Contains the electronics needed to perform drop detection, a DC motor/encoder for capping, wiping and spitting and a stepper motor for priming. Front Panel: is the user interface. It consists of an LCD display, a key panel and six LEDs. Power Supply Unit (PSU) The PSU is used to supply the power required by the product in any condition.The PSU provides +5 V, +3.
Functional Overview Soft Power-Off Switch There is a power-off switch on the front panel to switch OFF the product in a controlled way. When the switch is actuated the firmware turns off several subsystems and stores information about the product in the EEROM, then it grounds the soft power off signal to the PSU to switch off the product.
Functional Overview n menus: Back, Enter, Up, Down and Menu. (You can print a demo plot called Menu to get the complete menu tree). 1 key on the upper right corner is used to switch the power ON and OFF. This key is called soft power ON/OFF in contrast to the hard power ON/OFF switch located at the back of the printer. The beeper is used to provide audible feedback to the user.
Functional Overview Tubes System The Tubes System is the assembly that performs these functions: n Conduct the ink pumped from the Ink Cartridge to the Printhead. n Conduct the air from the pump into the Ink Cartridge. n Keep the ink in good condition until it is delivered to the printhead. n Avoid leaks and minimize ink on customer. The main functional groups of the Tubes System assembly are the tube routing, the tubes and the printhead fluid interconnect.
Functional Overview Air Pressurization System (APS) The APS is the system that provides and controls the pressurization of the ink in the Ink Cartridges. The key “mission” of this system is to ensure the minimum required ink pressure at the inlet to each Printhead respectively at the required print rates.
Functional Overview remaining ink. These two coils are part of a flex PCB that also includes the connection pads and the ink leak detection pads. The ISS board includes the electronics required to measure the level of ink using this variable transformer. The circuit generates the excitation signal applied to the primary coil and reads both the current flowing through the primary coil and the voltage induced at the secondary coil. The secondary voltage vs.
Functional Overview At the ink collector there are two metallic pins between which the resistance is checked. When there is no leakage, there will be air present and the resistance measured will be high. In case of leakage, the collector will contain ink and there will be a potential short circuit between both electrodes through the ink, and the ink leak will detected.
Functional Overview Cap The purpose of the caps is to prevent the nozzles from drying out while the printer is idle. The caps seal off the printhead, forming a closed, high humidity chamber with small volume that is vented to ambient through a long and narrow passage. The caps self-align to the printheads by referencing features on each printhead.
Functional Overview Snout Wiper Snout wiper is used to clean the ink accumulation that happens on the snout of the pen (vertical corner on the interconnect side) because of wiping operation. This is done to avoid spreading this ink over the interconnect when replacing the pen and generating ink shorts between interconnect pads. Handle and Printable Label The handle is used to remove and install the PHC.
