3.2 Troubleshooting for Printer

This section describes repair / service of the Printer Mechanism. Listed below are various problems which may occur, observations of such problems, check point and remedies. For the pertinent observation, check the functions of the parts in question according to Check Point.

Table 3-3. Printer Errors

Observation Cause Remedy

Ink shortage / Ink out

Paper out • When Printer cannot load

• If any ink cartridge comes close to Ink out, Printer continues printing in ink shortage status.

• If cartridge is completely empty, Printer indicates ink out error and stop printing.

paper, paper out error is indicated.

• Paper stops in front of PE detector or paper is not loaded.

• Paper is loaded without adjusting paper to right edge guide.

• Start cleaning execution command on Panel or by Utility.

• Carriage automatically moves to replacement position.

• Replace ink cartridge with a new one.

(1)Set paper on tray if paper is out. (2)If paper is stopped midway, pull paper

out and check that paper is not folded. Loosen paper well and set it again with edge guide adjusted to paper width.

(3)Execute “Load/Eject”.

• Clean paper loading roller. Or replace paper loading roller.

• Check that gears for ASF are engaged correctly.

Table 3-3. Printer Errors (continued)

Observation Cause Remedy

Paper jam When paper is not ejected,

paper jam error is indicated.

Ink cartridge out • If Ink cartridge is not

correctly set, printer indicates ink cartridge out error.

Maintenance error

Fatal error

Waste ink overflow indication is displayed if the total amount of ink consumed by cleaning and/or flushing has exceeded the predetermined limit.

• Carriage error:

• Home of carriage can not be recognized.

• Abnormal external power was applied to carriage or carriage operation is obstructed during printing.

• PF error:

PF motor does not operate adequately to feed paper by the required distance.

• Select “Load/Eject” from menu and execute it.

(1)Open the printer cover and remove

with hand all the paper inside the printer and all the set paper if there is paper on the way of loading.

(2)Check that there is no paper in the

printer and set paper again and execute paper loading and paper ejection. Then, this error display will be cleared and if there is print data, print operation will start.

• Check whether Platen gap is correct value. (Refer to “Adjustment” on

page 57)

• Check CSIC connection circuit.

• Replace ink cartridge.
