Pressing the Resume button will exit the error without ink tank replacement, however, ink may run out during printing. 5 times The print head is not installed [1401], or it is not properly installed (EEPROM data of the print head is faulty) [1403/1405]. Install the print head properly, and close the front cover. Or, with the print head installed, turn the printer off and on. No CD-R tray feeder (during CD-R printing). [1850/1855] Set the CD-R tray and tray feeder properly, and press the Resume button. 6 times *1 Presence of the CD-R tray feeder (during paper printing). [1851/1856] Remove the CD-R tray feeder, and press the Resume button. 7 times *1 No CD-R or DVD-R. [1002] After setting a CD-R or DVD-R in the tray, set the tray in the tray feeder, and press the Resume button. 8 times Warning: The waste ink absorber becomes almost full (approx. 95% of the maximum capacity). [1700] Pressing the Resume button will exit the error, and enable printing. In repair servicing, replace the bottom case unit (QM2-0663), or 5-item set of the ink absorbers (QC1-2232/2233/2234/2235/2236). The service call error, indicating the waste ink absorber is full, is likely to occur soon. 9 times The connected digital camera or digital video camera does not support Camera Direct Printing. [2001] After removing the cable between the camera and the printer, press the Resume button, and re-connect the cable. When connected to a Direct Print supported camera, the green LED blinks 2 times. 11 times Automatic print head alignment failure. [2500] Press the Resume button, and after confirming the following, perform print head alignment again: - Set an appropriate type and size of paper (plain paper, A4 or letter). - Check that the nozzle check pattern is properly printed (all ink ejected, no faint printing) - Check that the paper output slot is not exposed to light. * 1 : Only for the model supporting CD-R printing (i905D only) 1 - 4
