Hello everyone. after changing an black drum and developer unit in KM c452 and printed a sample page (a3) the page is printed with a fade stip almost in the center. this happens only on black color
any advice ?
see image for better view of the problem...scan2.jpg
The first thing I would do is clean the black printhead.
what do you mean clean the print head ?
The slit glass on the laser assembly (print head) that writes the image to the drum. Use the long, flat, plastic, stick with the white pad on the end to clean this glass.
If I remember correctly it can be found underneath a cover in the front of the top paper cassette.
Page 9-13 of the Copy Operations guide from KonicaMinolta self help manuals section.
Confirm that. Clean the slit glasses. =^..^=Originally Posted by darry1322
If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

i cleaned the glass from the inside (removed the unit to do it better) but nothing...
any other ideas ? maybe a faulty developer unit?
Push a piece of paper between the dev roller and doctor blade and move from side to side. This should release built up toner.

ok tryied that the problem is less visible but still there.
the unit is brand new ( 500 a4 prints)
Re: Km c452 fade black zone in center of page...
I had some of those myself, the laser unit might be dirty(i mean the glass on top) if you had the machine running for a long time without service or some other toner have been in use that would be my first guess, second would be what nei said before but its not always efective depending on the difference you had before, only way is to change the unit again. loads of luck with that.
cleaned the laser glass again
run 250 more prints (b/w)
and this is the result.
