Spots on page

I have been getting tiny black spots on my printed pages. I opened the printer and took out the cartridge and noticed lots of black dust or toner. Help.

Re: spots on page

You need to clean the drum unit (use a soft cloth and/or a soft paint brush) and also slide the blue slider a couple of times to clean the wire.

Clean out the toner spillage as best as you can. Your not supposed to use one, but a vacuum is the best method to suck it up. Once clean, replace the image drum (photoconductor unit). Also make sure the laser lens glass panel is clean - wipe it with a soft cloth or tissue.

Dirty pages

sounds like a dodgy black toner - is it a 3rd party toner - had this quite a lot myself at work with cheaper cartridges. to print a cleaning page just flick through the menu to diagnostics or print quality - in here you should find some cleaning tools of the machine

Black spots on each page

A laser printer has its rollers (which I believe you said you cleaned...very important) and the cartridge you put in the printer has rollers too! Carefully check them and the wiper on the cartridge. If all of those things are clean, then you should get clean copy!

Streaks and black spots on printed pages

Try cleaning the laser lens using the laser lens cleaning wand. However, it is likely that your black cartridge needs to be replaced based on the troubleshooting from the Minolta manual. Sorry,

We have just changed the photoconductor unit on our Epson Aculaser CX11NF printer. When we print or copy, we get coloured spots on the right hand side of the page

Oh-ho! The coloured spots are what is known as "traffic lights". To be sure these are the symptoms: You will have a black spot then a slightly larger gap then the three colours regularly spaced, the pattern will repeat every 150mm or so. If you print a black only page then only the black dot will appear, print with any colours and all four dots will be printed. It is caused by a tiny/slight scratch on the photoconductor (PCU) drum (usually caused by mishandling, a loose or foreign object inside the printer or even trying to print on stapled paper!). Polishing the drum using a very soft dry cloth can often help to get rid of the scratch, but remember to keep it away from any bright light as this will damage the sensitivity of the drum. The traffic lights will be in line with the scratch so concentrate your efforts in that area. Also, while the PCU is out, take a good look inside the printer for any loose or protruding objects, rotate the toner cartridges from above with the front cover closed (opening the front locks the cartridge carousel in position). I sincerely hope this helps as the only other remedy is to replace the PCU with a new one.

Black ink not printing

Fix ink cartridge
I had same problem. I must have ran the clean cycle more than 30-50 times over a period of days. That never made any difference. I was about to toss the whole thing but figured I would try one more thing. If it didn't work I would be in no worse shape. Here is what I did.
Took an almost empty black cartridge and inject a lot of 100% Acetone to dilute ink. Left some black in it since I didn't want to think it was empty. Inserted this cartridge and ran the cleaning a few time. IT WORKED. I used my word processor program and filled a page with large bold font characters and printed a page or two. Each page cleared more nozzles. After doing this cleaning/printing a number of time, I put in the full good cartridge. Ran the cleaning a few time to eject any of the Acetone diluted ink. Ran the printed page a few time to remove more of the diluted ink.
Everything seems to work now.

Out of toner........ but not really.....

Print a Supplies Status page to see the actual pages printed...

To print the Supplies Status page from the printer, on the printer control panel, select
Reports Menu, Supplies Status, and then Print Supplies Status page.

If the page count from the Supplies Status page indicates that the toner should not be in need of replacement then you have a bad cartridge. Actually, the cartridge is probably fine but the chip on the cartridge has got a problem. Return the cartridge to O.D. and get another one. Unfortunately, chips that don't work properly in not all that unusual so HP has a pretty easy return policy.

Hope this helps.
