Chapter 2: Basic Operation This describes the sequence of basic operations from switching on the power to performing printing.
2-1 Switching the Power On and Off Switching On the Power Leave the main power switch turned on, and use the [POWER] key to switch the power on and off in day-today use. Points to Keep in Mind When Switching the Power On and Off Do not switch off the main power while the sub power is switched on. The print heads may be left uncapped (that is, the printhead carriage may remain over the platen).
2-1 Switching the Power On and Off Switching Off the Power at the End of the Day Press and hold down the [POWER] key for one second or longer to switch off the sub power. Leave the pinch rollers raised when not in use. Deformation may occur if left lowered for a prolonged period.
2-2 Loading Media Be sure to install the media guide when loading roll media. Otherwise the roll may fall and cause injury. Load roll media at the proper position. Otherwise the roll may fall, resulting in injury. When the reinforcement pipe is inserted into the paper tube, do not angle the roll media. The reinforcement pipe may protrude from the roll media and cause injury. Rail portion Do not touch the rail or the inner side of the left and right cover.
2-2 Loading Media 4 Fit the right-hand media flange all the way into the hole on the right-hand side of the roll media, and tighten the retainer screw to secure in place. Roll media Media flange (right) Media flange Roll media When roll media sag severely, use the reinforcement pipe inserted into the roll media. After use, remove the reinforcement pipe from the paper tube. 2 in. 5 3 in. Reinforcement pipe Move the media clamps to the two ends of the platen.
2-2 Loading Media 7 Grasp the center of the end of the media at the front of the machine, and slowly pull the media out straight to the position shown in the figure. 8 Slowly turn the media flanges at the back of the machine to pull back the media to the position shown in the figure. When you roll back the media until the sensor comes into view, a tight seal is formed between the media and the platen, and the media is stretched taut. Sensor Entire media stretched taut Pull back the media here.
2-2 Loading Media When the machine will remain unused for an extended period, remove roll media from the machine and store it. If roll media is left mounted on the machine for an extended period, these entire roll may warp, resulting in poor printed image quality or motor errors. When transparent media is loaded, it is necessary to set [SHEET TYPE] to [CLEAR]. For more information, see "4-5 Using Transparent Media.
2-2 Loading Media Loading Sheet Media Before attempting to load sheet media, check the following points. Front View Line up the right edge of the media with the guide line, and align the front edge with the location shown in the figure. If the front edge of the media is cut at an angle, load the media so that its edge is lined up straight with the guide line. Guide line Media Align here. Be sure to line up the right-hand edge of the media with the guide line.
2-2 Loading Media When Loading Thick Media Media that is thick or that warps easily may lead to problems with media feed or jamming. When you are using such media, adjust the height of the print heads. When the height of the print head has been adjusted, it is necessary to perform bidirectional correction. For more information about bidirectional correction, refer to "4-6 Making Corrections for Printing" and see "Bidirectional Correction.
2-2 Loading Media When Loading Media That Warps Easily When you are loading media whose left and right edges are prone to warping, use the media clamps. The media clamps can be used to secure media that is up to 0.7 mm (0.027 in.) or so in thickness. The following media cannot be used even when secured in place by the media clamps.
2-2 Loading Media Separating the Media Make sure the [SETUP] LED lights up. To cut off a printed portion from the roll, hold down the [SHEET CUT] key for at least one second. The piece is cut off at the present location of the printing-start line. This step is not necessary when cutoff is performed automatically by sending a media-cutoff command from the computer. Knife guide Depending on the composition of the media, cutoff may not be possible. The media is cut off here.
2-3 Printing Do not open the front cover. Opening the front cover while printing is in progress causes an emergency stop. This means that printing may not be carried out correctly even if operation is resumed, due to drop-out or misalignment of the image. During printing, do not touch the portion of the media that's already been discharged. Doing so may obstruct media feed or cause the media to rub against the heads, which may result in a paper jam or damage to the heads.
2-3 Printing Performing a Printing Test Before starting to print, carry out a printing test to check the state of the head. Problems such as missing dots may reduce the printing quality. If the test results show a problem, carry out head cleaning to restore the head to its normal state. 1 Press and hold the [TEST PRINT] key for at least one second to carry out a printing test. The test pattern is printed. 2 If dot drop-out is present, clean the heads.

Chapter 3: Using the Print Heater This section describes how to print while using the print heater and the like.
3-1 Switching the Print Heater On and Off Switching On the Print Heater 1 Switch on the power switch for the print heater. 2 The [C1] indicator lights up. After the temperature display panel flashes for a short interval, both [SV] and [PV] light up and indicate their values. The print heater starts operating. When the temperature display panel shows characters other than numerical figures, such as UUUU or LLLL, immediately switch off the print heater and contact your authorized Roland DG Corp.
3-2 Loading Media About the Ambient Temperature During Print Heater Use To ensure stable printing quality, we recommend use in an environment where the ambient temperature is 20˚C (68˚F) or higher. At low temperatures, warm-up may take a long time, or the temperature may fail to reach the preset value, or large differences in temperature may occur. Inadequate temperature may result in coarse printing. If the media fails to warm up sufficiently, try setting the print heater to a higher temperature.
3-3 Printing Printing Before performing printing, set the preset temperature to 40˚C (104˚F) and wait until media becomes sufficiently warm. The recommended ambient temperature for ensuring acceptable quality when performing printing is 20 to 32˚C (68 to 89.6˚F). When the ambient temperature is less than 20˚C, the media doesn't heat up enough to ensure acceptable quality. In such cases, set the preset temperature to higher value. 1 After loading media, set [SV] to 40˚C.
Chapter 4: A Wide Variety of Operations This section describes a wide variety of operations and functions, grouped by task.
4-1 Replacing the Ink Cartridges Care and Handling of Ink Cartridges • Do not use anything other ECO-SOL INK cartridge.

Cleaning the Print heads 1 Load media for printing-test use. 2 Press the [CLEANING] key, and press the [ ] key to select the printing-head group to clean. Press the [ENTER] key to start head cleaning.
5-1 Cleaning the Print heads If Drop-out Persists Even After Carrying Out Cleaning Several Times Perform head cleaning only when there is dot drop-out (gaps) or printing becomes faint. Performing head cleaning more than necessary subjects the heads to wear and consumes ink. In particular, cleaning performed at the [POWERFUL] menu for [HEAD CLEANING] can cause premature head wear and consume large amounts of ink. 1 Load media for printing-test use.
5-2 Cleaning Using the Cleaning Kit Cleaning using the cleaning kit should be carried out when automatic cleaning and forced cleaning from the [HEAD CLEANING] menu fail to correct image drop-out. Remove any ink buildup of dust or grime around the print heads, which can cause image drop-out or ink drips. We also recommend performing periodic cleaning using the cleaning kit to prevent problems like these during printing.
5-2 Cleaning Using the Cleaning Kit 6 To discharge static electricity from your body, touch the location shown in the figure. 7 Clean the heads and the area around the heads on the left side of the machine. Use a cleaning stick to wipe off any grime from the stainlesssteel frame for the heads and the plastic areas on either side of the heads. Be sure to use one of the included cleaning sticks. Do not touch the nozzle surface of the heads.
5-2 Cleaning Using the Cleaning Kit 10 Wipers Clean the wiper. Use a cleaning stick to wipe away any buildup of dust and grime from the wiper. Replacing the Wiper If the message [REPLACE WIPER] appears on the display, replace the wiper with a new one. As a rule of thumb, the message prompting you to replace the wiper appears when cleaning has been performed 500 times (with [ALL] selected for head cleaning). For information on how to replace the wiper, see "5-3 Replacing the Wiper.

Doing so may cause burns because the platen is hot. Never clean with solvents (such as benzine or thinners). Doing so may cause fire. • When carrying out any cleaning other than cleaning using cleaning sticks, switch off the main power. Before turning off the main power, press the [POWER] key to switch off the sub power.
5-5 Disposing of Discharged Ink The bottle stand for the drain bottle is provided with a window to help determine when discharged ink needs to be disposed. When the discharged ink is within this range, dispose of it. If discharged ink is allowed to exceed this range, it may spill when the bottle is removed. Dispose of ink in the drain bottle as described below. Discharged ink is flammable and contains toxic ingredients. Do not attempt to incinerate discharged ink or discard it with ordinary trash.
5-6 How to Replace the Separating Knife Do not touch the tip of the separating knife with your fingers. Doing so may result in injury. Do not touch the control panel while head cleaning or other cleaning is in progress. The print-head carriage may move and cause injury. Do not try to pull out the print-head carriage by hand. The print-head carriage is pulled out automatically through menu operation.
5-7 When Moving the Unit Procedures from Preparing to Move Through Reinstalling To move the machine, you must completely drain all ink inside the machine and secure the print heads in place with retainers to protect them. Attempting to move the machine without first doing this may result in damage to internal components due to leaking ink or damage to the heads. This operation requires eight unused SOL INK cleaning cartridges. Have these on hand before you start. Be sure to use SOL INK cleaning cartridges.
5-7 When Moving the Unit 2. Secure the print heads in place. 1 Remove the drain bottle and discard the discharged ink. (Refer to "5-5 Disposing of Discharged Ink.") Pull out the drain tube from the bottle stand and attach the stopper. Stopper 2 3 Flip the loading lever to the rear. Drain tube Secure the print heads in place using the retainers.

Chapter 7: What to Do If... This section describes error messages that may appear on the display and how to resolve problems that can occur during operation.
7-1 What to Do If... The Machine Doesn't Run The power does not switch on. Is the main power switched on? If the power does not come on when you press the [POWER] key, make sure the main power is switched on, then press the [POWER] key again. Printing doesn't start when data is sent. Are the network settings correct? Make sure there are no errors in the network settings. For more information about making the connection to a network, see "Roland-PrintServer Network Settings Guide.
7-1 What to Do If... Clean, Attractive Printing Is Impossible If drop-out occurs with printed images. Clean the print heads (see "5-1 Cleaning the Print Heads"). The printed images are not clean. Clean the platen and pinch rollers. (See "5-4 Other Cleaning Tasks") The print heads scrape the surface of the media. Is the loaded media very thick? If media feed is not smooth because the media catches on the head, then adjust the height of the print heads.
7-1 What to Do If... During printing, ink drips from the print-head carriage and soils the media (the printing surface) The following may cause ink to drip on the media during printing. • Dust or fiber-containing grime around the heads may have absorbed ink. • The heads scraping the media may have caused ink to fail to be discharged, resulting in ink buildup in the heads. If this happens, refer to "5-2 Cleaning Using the Cleaning Kit" and clean the heads. We recommend carrying out periodic head cleaning.
7-1 What to Do If... Media Wrinkles or Warps Media Wrinkles When Performing Printing Was the media allowed to stand while heated? Depending on the type of media, it may wrinkle when performing printing after it is left on the platen for 30 minutes to an hour with the print heater temperature at 40˚C. When you are not printing continuously, remove the media or reduce the preset temperature to 30˚C.
7-1 What to Do If... What to Do If the Print-head Carriage Does Not Operate During operation, if for some reason the print-head carriage does not return to the standby position, then following the procedure, cap the print heads, and contact the your authorized Roland DG Corp. dealer or service center. If the print-head carriage is allowed to stand for a prolonged period with the print heads uncapped (that is with the printhead carriage over the platen), the heads may become clogged or even damaged.
7-1 What to Do If... 5 When the print-head carriage comes into contact with the caps, rotate the pipe one or two turns more. Make sure the print-head carriage and the caps are touching, then contact your authorized Roland DG Corp. dealer or service center. Chapter 7: What to Do If...
