Print-media specifications This section contains information about specifications for the quality of print media, guidelines for print media usage, and guidelines for print media storage. General guidelines Some print media might meet all of the guidelines in this manual and still not produce satisfactory results. This problem might be the result of improper handling, unacceptable temperature and humidity levels, or other variables over which Hewlett-Packard has no control.
Care should be taken not to purchase more paper than can be easily used in a short time (about three months). Paper stored for long periods can experience heat and moisture extremes, which can cause damage. Planning is important to prevent damage to a large supply of paper. Unopened paper in sealed reams can remain stable for several months before use. Opened packages of paper have more potential for environmental damage, especially if they are not wrapped with a moisture-proof barrier.
depends upon the quality of the envelopes. When selecting envelopes, consider the following components: ● Weight: The weight of the envelope paper should not exceed 90 g/m2 (24 lb) or jamming might occur. ● Construction: Before printing, envelopes should lie flat with less than 6 mm (0.25 inch) curl, and should not contain air. ● Condition: Envelopes should not be wrinkled, nicked, or otherwise damaged. ● Temperature: Use envelopes that are compatible with the heat and pressure of the printer.
Labels Select the type of label that you are using from the Print dialog box or the printer driver. CAUTION To avoid damaging the printer, use only labels that are recommended for laser printers. To prevent serious jams, always use Tray 1 or Tray 2 to print on labels. Never print on the same sheet of labels more than once or print on a partial sheet of labels.

Storing supplies Follow these guidelines for storing print cartridges: ● Do not remove the print cartridge from its package until you are ready to use it. CAUTION To prevent damage, do not expose the print cartridge to light for more than a few minutes. ● See Environmental specifications on page 273 for operating and storage temperature ranges. ● Store the supply in a horizontal position. ● Store the supply in a dark, dry location away from heat and magnetic sources.
Cleaning the printer During the printing process, paper, toner and dust particles can accumulate inside the printer. Over time, this buildup can cause print-quality problems such as toner specks or smearing. This printer has a cleaning mode that can correct and prevent these types of problems. This printer has two processes for generating cleaning pages: one is automatically generated and one is manually generated.
To clean the fuser using HP Toolbox NOTE Use the following procedure to clean the fuser using the HP Toolbox. To clean the engine when the computer is running an operating system that does not support HP Toolbox, see the late-breaking Readme on the root of the CD-ROM, or visit http://www.hp.com/support/ clj1600. 1. Make sure that the printer is turned on and in the Ready state. 2. Open the HP Toolbox. 3. On the Troubleshooting tab, click Troubleshooting Tools, and then click Print.
Calibrating the printer The printer automatically calibrates at various times. You can adjust the calibration settings by using the HP Toolbox. Environmental differences or aging print cartridges might cause fluctuations in image density. The printer accounts for this with image stabilization control. The printer automatically calibrates at various times to maintain the highest level of print quality. You can also request a calibration by using the HP Toolbox.
4 Operational theory This chapter contains information about the following topics.
Engine control system Basic sequence of operation The operational sequence of the printer is controlled by the microcomputer on the DC controller printed circuit board (PCB). The purposes of each period, from power-on until the main motor stops after the completion of printing, are listed below. See General timing chart on page 56 for a detailed timing chart. Table 4-1 Basic operational sequence Period Purpose Remarks WAIT (wait period) From power-on until the end of the main motor initial drive.
Figure 4-1 Engine control system Power-on sequence The power-on sequence is for the purpose of the printer initialization and checking for possible malfunctions. The following is the sequence from when the printer is turned on until it enters STBY mode. 1. Power on 2. Central processing unit (CPU) initialization 3. ASIC initialization 4. Video interface communication start 5. Residual paper check by each sensor signaling paper presence 6.
The specifications of each motor are listed in the following table.
Image formation system The image formation system serves as the nerve center of the printer and forms a toner image on paper. It is controlled by the DC controller. The DC controller controls the laser/scanner unit and the high-voltage power supply PCB to form an image on paper according to the VIDEO signals (VDO, / VDO) upon reception of a print command from the formatter. There is a memory tag inside each cartridge. The memory tags read and write data according to the command from the DC controller.
Figure 4-2 Image formation system 40 Chapter 4 Operational theory ENWW
Image formation process Figure 4-3 Image formation process ENWW Image formation system 41
The principal process of image formation is described here. The print process can be broadly divided into 5 stages with 7 steps. A toner image is formed on paper as it goes through each process. The following figure illustrates the stages and steps of the print process as follows. 1. Electrostatic latent image formation stage Forms an electrostatic latent image on the photosensitive drum. Step 1: Primary charging Step 2: Laser beam exposure 2.
Figure 4-4 Latent image formation Laser/scanner system The laser/scanner system forms latent images on the photosensitive drum according to the VIDEO signals sent from the formatter. It consists of the laser driver PCB, the scanner motor, and so forth. The figure below illustrates the laser/scanner unit. Figure 4-5 Laser beam exposure Developing stage The electrostatic latent image on the photosensitive drum surface is visualized by applying the toner in this process.
Figure 4-6 Developing stage The toner has an insulating property and has negative charge potential from friction with the rotating developing cylinder and the developing blade surface. The area of the photosensitive drum, where the laser beam is exposed, has higher potential than the toner, which is charged negatively on the cylinder.
Figure 4-7 Print cartridge structure Transfer belt (ETB) The ETB unit feeds paper as well as transfers toner onto the paper. The ETB unit consists of the ETB, ETB feed roller, ETB driven roller, and color misregistration/ density sensor unit. As the main motor rotates the ETB feed roller, the ETB feed roller rotates the ETB belt. The transfer roller and the ETB driven roller are engaged with the ETB.
Figure 4-8 ETB unit Transfer stage The transfer stage is to transfer the toner image on the photosensitive drum surface onto paper.
The toner on the photosensitive drum surface is transferred onto the paper according to the positive charge from the back side of the paper. Each color’s toner image is transferred in order of M, C, Y, and K, and forms one toner image overlaying one color’s image on another. Separation stage Figure 4-10 Separation stage The paper is separated from the drum by its elasticity (Curvature Separation).
not require the power supply during STBY mode, and saves energy. As for the printer, the DC positive bias is applied to the fuser pressure roller, so the transferred toner stays harder on the paper and toner scattering to the fuser film (offset) is prevented.
Pickup and feed system The pickup/feed system, which picks up and feeds paper, consists of the various feed rollers. This printer has two pickup sources: the cassette and the manual feed slot, and one delivery source: the face-down tray.

Check the power source by plugging the device directly into the wall or into a different outlet. 4. Test the outlet or connect another device to the outlet to verify that the outlet is functioning.
Clearing jams This section contains information about clearing jams. Paper path Figure 6-1 Paper path For paper path sensor locations, see Figure 4-12 Paper pickup and feed system on page 50.
Common causes of paper jams Occasionally, paper or other print media can become jammed during a print job. Some causes include the following events: Cause Solution The input trays are loaded improperly or overfilled. Remove any excess paper from the input tray. Make sure that the paper does not exceed the maximum stack height mark in the input tray. Tray 2 or optional Tray 3 is opened during a print job. Make sure that Tray 2 or optional Tray 3 is closed.
Where to look for jams Jams can occur in these locations: ● Inside the printer ● In input areas ● In the output area ● Paper path The following illustration identifies the stages when jams can occur.
Find and remove the jam by using the instructions on the following pages. If the location of the jam is not obvious, first look inside the printer. Loose toner might remain in the printer after a jam. This problem should resolve itself after a few sheets have been printed. Each section below corresponds to an area where a paper jam could occur. Use the following procedures to clear the jam. In all cases, grasp the jammed paper by both corners and pull slowly to remove the paper.
2. Carefully grasp the jammed paper by both corners and pull slowly to remove the paper. 3. Close the front door. Input jams Tray 1 If the jammed paper is easily accessible from the outside of the printer, grasp both edges of the paper and firmly pull to remove. Otherwise, follow the directions for Tray 2.
Tray 2 Open the front door of the printer and remove paper as indicated on the jam instruction label, located on the interior right side of the printer. Input jams are indicated on the label with the number 3. Figure 6-3 Tray 2 input jam label Output jams Jams in the top bin CAUTION Jams in these areas might result in loose toner on the page. If you get toner on your clothes or hands, wash them in cold water. (Hot water will set the toner into the fabric.) 1.
2. Open and close the front door. Pickup delay jam The printer performs the retry control, which executes the pickup operation three times, to retrieve the pickup delay jam caused by the pickup error. When the registration paper sensor (SR1) does not detect the leading edge of the paper within approximately 2.5 seconds (4.5 seconds for optional cassette) after the pickup solenoid (SL1) is turned ON, the CPU tries to pick up the paper three times.
Door open jam The CPU determines the door open jam, when either the pre-fuser paper sensor (SR5) or the fuser delivery paper width sensor (SR4) detects paper when a door open is detected.
Print problems Getting information The following sections contain information about control panel messages, error reports, and available service menus. Control panel messages The majority of the control-panel messages are intended to guide the user through typical operation.
