Hi,
The following problem is occuring on my Laserjet IIP Plus. A new toner cartridge had been installed 6 months ago and has been working fine until a week ago.
The problem (see bottom for sample images):
It's probably best to describe what happens when I print out a page containing only a uniform grey background. The leading inch is blank where it should be uniform grey. Immediately after this leading blank space is a heavy dark horizontal line (about 2mm thick) spanning the defined print-width area of the page. It almost seems like a blade has pushed all the toner from above to this spot, where it then fused. For the remaining length of the page, the uniform grey background was printed, however there are light horizontal bands of varying thickness, but seem periodic. These bands are probably rub-offs from the built-up toner that caused the thick dark line mentioned previously. Additionally, it seems that the longer the printer is inactive, the larger the white space at the top, however, thick dark lines sometimes occur in the upper third of the page. Printing multiple (10+) copies in a row does not solve the problem.
Also to note, when printing text documents, certain lines of text appear 'squished' horizontally, usually in the top third of the page. Horizontal streaks of about 5mm thick appear usually in the top third of the page as well.
In all cases, the toner is fusing properly. Running a cleaning sheet through doesn't solve the problem.
On the backside of the page are faint, periodic bands approx. 2 inches apart. The width of these bands are not constant and vary from 3mm to 10mm.
I can't determine if this is a problem with the toner cartridge (the toner cartidge actually includes the drum for this printer), or the mechanics of the printer itself. If anyone can point out what the problem is, I'd really appreciate it.
Thanks,
Mike
