Blank Copy MP171SPF
Hi.. Just finished servicing a MP171SPF (no replacements) just a general cleaning and vacuuming as the toner had spilt inside the machine. Now there is no print/copy. Even the "counter copy (from engine)" is blank. Tried changing PCU's from different machines but no luck. Pls give me some suggestions. Thanks in advance.

Hi there!
On the drum-shaft is black grease, clean it, also the contact inside the drum (q-tip). Take a close look at the little groundplate at the back of the paper-cassette. If itīs bend and not in contact with the frame you can get very strange efects ( bad or no image, sc-codes, etc...).
Greetings...

Thank you for your response Zelderman, I checked the cassette earth plate and cleaned the grease on the drum shaft but still same 'blank copy' issue. Greeting to U too.

Hi
Stupid suggestion - but here goes:
You didn't leave anything (like a cloth) in the cavity to the left of the toner hopper? This will effectively stop the laser light from reaching the drum = blank copy.
Else I would suggest starting a copy then stop the machine midway to see if there is any image on the drum - if so it is a transfer issue (check the right door).
If blank then there is an issue between laser and drum.

Re: Blank Copy MP171SPF
Maybe anithere stupid question but is there a toner bottle in the machine? Some of these entry level machines have a lever at the back of the toner hopper that kills the laser is there is no bottle in the tray.
