HP 8550 Laser

I have got one of these second use, very low page count.

The config shows 75% for all consumables, except the below:

1 x Yellow at 0%
Drum Kit at 19%

Drum kit shows on screen as 'requires replacing'.

Print quality is good, but a little bandy in places, bluish lines on the page one particular area each time.

Is this likely to be the drum kit or the lack of toner?

Very new to lasers, expecially this type with multiple toners and drums, transfer kits etc etc.

Thanks for any pointers as to what to look to replace first.......the replacements cost more than some printers!

Definitely the drum. When you start getting bands or marks in the same place on multiple pages, that is the cardinal mark for the drum being bad.

Thanks, I thought it may be, but as it still said 19%, I wasn't too sure.

It is difficult to judge the toner, as I believe you manually reset the % count yourself when you replace the toner, so although the yellow says 0%, it does still print perfectly fine with pure yellow, looking at the print on the config page.
