The PGBK tank is 3rd party as are all the tanks on the printer. The "white tissue" test show deep black ink in a square pattern and a long line pattern next to the square one, so it seems ink is getting through. The ink levels in the PGBK tank decreased during the tests as did all the other tanks. I tried deep cleaning PBGK a couple of times, no luck.
C M Y and BK printed but there was no test pattern for PGBK. I tried normal cleaning then test patterns 4 times. I soaked the print head over night in distilled water and soaked the inlet holes as well.Īfter drying I reinstalled and tried to print with no luck. Yesterday the printer failed to print text from various files, pdf, wordpad, note pad etc. I suspect it has been not really working well for a while but still able to print text. I now notice that the ink level of the PGBK has not decreased despite printing for a good bit. Not really deep black on the text and any colors look pale also. For the sensor that uses the sensor arm and the microswitch, the output of the sensor can be confirmed by moving them by the hand.My printing has been looking more and more washed out. In this test, the state of each sensor of this machine can be checked on the display. SENSOR TEST is selected from the H/W TEST menu. Use the BLACK print pattern to meke sure that the printout is free of white lines and unevenness on the other hand, use the SQUARE printout to make sure that the printout is free of image contraction, elongation, and soiling. For service work, be sure to use the BLACK pattern and the SQUARE pattern.
In this test, the printer unit will be used to print various patterns. PRINTINGįrom the FUNCTION menu, select PRINT TEST PATTERN. Stoppbotaning is pushed when coming off the test mode.įUNCTION → PRINT TEST PATTERN → CONT.
