Introduction

When "Ink Absorber Full" or "Ink Absorber Near Full" appears on your printer screen, it's time to replace the Flushing Box (and/or the Ink Absorber Box).

Given the difficulty of this repair, it might be advisable to replace the Ink Absorber Box first, see if that solves the problem, and then replace the Flushing Box if that doesn't work, even though it will save time to do both at once.

Conclusion

To reassemble your device, follow these instructions in reverse order. If you haven’t already, it’s recommended that you also replace the ink absorber box during reassembly.

Screw torques from the service manual have been included if you happen to have a torque screwdriver, but don’t worry about them if you don’t.

After reassembly, follow the following steps to reset the purge count in order to clear the “Ink Absorber Full” error:

  1. Plug the printer in and turn it on.
  2. Press the Home button (the house icon) on the front of the printer until the Maintenance Mode screen appears (approximately five seconds).
  3. Hold down the blank button at the bottom of the screen until a number keypad appears on the screen (approximately two seconds).
  4. Press *286 and 4 (you can use the onscreen keypad or the printer’s built-in keypad for this). The printer will beep and MAINTENANCE will appear on the screen.
  5. Press 8 and 0.
  6. Press the down arrow repeatedly until PURGE: (or FLUSHING:) appears on the screen.
  7. Press 278 and 3. The printer will beep and MAINTENANCE will again appear on the screen.
  8. Press 9 twice to exit maintenance mode and reboot the printer. You can also use this to start over if you make an error.

Hi there.

Great guide - although some pics of re-assembly and re-routing of the cables that were de-routed would have been very helpful. I am a complete novice and I followed this guide to the letter. I was successful in installing both boxes and re-assembling the printer so that on my initial power up it showed a fully usable touchscreen. However I then had a problem where it would not detect (any of) the ink cartridges.

I thought it might have been a loose connection and went as far back as re-seating the connections on the main PCB frame. After that the touchscreen display just remained blank.

I can’t think what I could have screwed up in re-seating things. One step forward - two steps back !

If anyone reads this and has some idea I would appreciate any assistance.

Cheers

When fixing the tube support plate be careful to have the blck cables of the switchback sensor harness pulled out as far as possible, it will be stuck under the plate and too short to plug it in again.

Désolé, je ne peux pas vous aider avec le problème "dl rom". Peut-être demander dans les forums? (Ceci provient de Google Translate; j'espère que cela a du sens.)
