Maintenance approach

The diagnostic information in this manual leads you to the correct field replaceable unit (FRU) or part. Use the error
codes, symptom tables, ser vice checks, and diagnostic aids to determine the sym ptom and repair the failure.

After you complet e the repair, perform tests as needed to ver ify the repair.

2. Diagnostic information

Power-On Self Test (POST) sequence

Plug the All-In- One int o an electrical outlet . The printer comes on automatically.
The All-In-One does a Power-On Self Test (POST) sequence.

1. The Power button, Copy button, and Color button lights come on.

2. The following will be displayed on the LCD screen sequentially:
Lexmark, Energy Star, and a bar indicating the remaining time for POST.

3. The purge pump runs simultaneously, and then shuts off.

4. The carrier moves off of the maintenance station simultaneously, and then returns.

5. Home Menu appears on the LCD screen with functional icons.

If any of these fail to occur, remove and reinstall the print cartridge, and then repeat the POST. If the POST remains
incomplete, then see “Service checks” on page 2-13. Find the symptom, and take corrective action.

Theory of operation

The printhead system consi sts of a singl e ½”ch ip wit h 640 nozzl es p er colo r . The ink i s suppl ied and s to red in i ndivi dual
felt-filled ink tanks. Upon inst allation of the tanks, the ink must be drawn from the tanks to the printhead chip. This is
accomplished by activating the pump to create a vacuum in the maintenance cap. The vacuum is held until al l ai r is
purged from the ink system.

Media is loaded into the input tra y where it is restrained by the friction buckler. The edge guides are adjusted to center
the media and ensure that it sits squarely in the tray. The media sensor detects media type (plain, photo, coat ed,
transparency) or paper- out. When a print job is received by the printer, an authenticat ion and maint enance operation is
invoked. During this operation, t he validity of the tanks and the ink l evel in each tank are verified by the RFID system.
The printhead is then prepared for printin g by wipi ng the surface of the chip and acti vating each nozzle.

The printing operation is initiated as the pick roll, which is driven by the pick motor, applies a lateral force to the top
sheet of the media. This force overcomes the resisting force of the fri ction buckler, allowing the single sheet to be
separated fr om the remaining media stack. The pick roller moves the media s heet to the feed roller, which hesitates to
rotate until sheet is squared with nip. This cor rects for skew. The pick roller is de-energized and now the feed roller
advances the media to t he pri n t zone. The printed image is appl ied in horizontal swaths as the carrier drives the
printhead acr oss the page. Successive swaths are overlaid by repea tedl y incrementing the fe ed roller a set distance
between print swaths. The printed media is driven out of the print zone by a nip formed by a driven exit roller and fine­pointed star wheels.

If a duplex print job is selected, th e med ia is not fully exit ed from the machine after the first side is pri nted, but is driven
just far enough to cle ar th e upper duplex gate. At this point the pi ck m otor is driven in reverse which l if ts the upper
duplex gate. The feed roller is then driven in rever se and the media is fed into the duplex guides where it is driven by
the duplex roller. Aft er the page is rotated in t he duplexer , it arrives back at the now forward-rotat ing feed roller and the
second side is printed.

Troubleshooting tables

The All-In-One has the capability to repor t in ternal errors. This is accomplished by displayi ng the error code on the
operator panel LCD. Als o, some errors are reported to host thr ough Extended NPA Device Status Alert (DSA). See
Consumer Printer Divi sion Host-Printer Communications Specification for more details on NPA and DSA.

There are four classes of All-In-One error s:

• POST errors

• Catastrophi c unrecoverable error s

• Paper handling errors

• Printhead errors

Note: Each error will have a unique, 4-digit code.
