Good afternoon all.
This is a multi-part question about the aforementioned printer.
Currently in use, is a HP 8150DN with over 420,000 pages to it's name with the duplexer running continuously. The duplexer has already undergone a change, as well as the normal 50,000 page services, 200,000 service and 350,000 page furnace replacement. A couple of questions.
1.) For any toner we change, the printer starts creating black lines; faint at first and much darker as time progresses. Having noticed that, when we take it offline, 10 minutes later it starts up again and then creates the streaky lines in a few minutes. Is this the toner's fault or is it the furnace ? (The toners are genuine HP.)
2.) Lately, when we print price catalogues (duplexer involved), the pages get jammed with high frequency. These mostly jam on their way for the reverse printout from what i could examine and yet, when you print from tray 1, as opposed to trays 2/3, the pages are perfectly fine. A guy told me it had something to do with the paper path sensors. Any easy fix around that or is it back into the pocket for more parts ?
300 split half-way for each answer ;)
