Question: HP Laser Jet1200 Print quality issue - dots on paper?

Answer #1
It is most likely a problem with the toner itself. If possibly exchange the cartridge for a new one. It never hurts to bring and example of the print to the vendor so they can be aware of the problem. That unit does not have a drum thus the only issue can be with the toner cartridge itself.

The issue is may be due to the improper communication between the printer cradle and the toner.Therefore, I suggest you to clean the printer as per the instructions provided in the web page.

Just print a Test Page of the Printer by right clicking on the Printer, selcting Properties and clicking on the Print Test Page Button. If still its the same issue, do the following.Go to printer properties again and you will have the printer maintenance tab. Mine is a Lexmark so yours will differ from mine but I'll tell you basically what you have to do. In the maintenance, you will find an option to Clear the Nozzle. Just insert an A4 Sheet and issue the command, while the printer is on. It should start to clear the nozzle by printing some texts. After it has finished, try printing a test page. If your printer cartridge nozzle had a problem then, your problem should have been solved by now but, if still the problem occurs that means, your Cartridge Nozzles are aligned incorrectly (Physical Problem).Ask a replacement from your vendor. They may view the Nozzle's physical appearance and give you a new one.BYE

There are a couple possible causes to your issue, but the first thing you should do is look at the last change you made, meaning your cartridge.A defective image drum, primary charge roller, padding powder, or remnants of a ripped or torn toner seal can all cause the issue you described. A damaged transfer roller (located under where the cartridge sits may also cause similar issues but is more likely to cause missing print areas.)One should note that new cartridges take 15-20 pages before any padding powder works its way out of them and the cartridge prints normally.My first suggestion is to shake in a side to side motion your old toner cartridge (while in a light protective anti static bag) and then re-install it for a few test prints. (this should allow for one or two printouts before the cartridge registers toner out again.)If your problem goes away, then it was the cartridge, and you should return it as defective for a replacement.Another common issue I see a good deal is a damaged or toner caked fuser.You can trouble shoot this by printing 15-20 blank pages.If the issue slowly begins to disappear then its possible that you simply had a build up on the fuser of toner, however if the problem resurfaces after just one printout, then the issue could still be the primary charge roller in the cartridge.The bad thing about the PCR being bad is that it can leave excess toner on the fuser and mimick a fuser issue until the residue is removed.For an absolute failsafe solution, return the cartridge as defective (which it likely is) and print the blank pages.After all of that if your issue STILL isn't resolved then I would say theres a good likelyhood the fuser is damaged. THere is a VERY fragile teflon sleeve on that unit, which if damaged, not only can be problomatic but can be a fire hazard as well because it allows for direct contact with the fusers heating element and paper. The fuser will need to be replaced immediately.You can visually examine the fuser by opening the back door and shining a light into the unit. look for a grey plastic sleave turn the unit off and then back on again to cause it to start. Be carefull not to shine the light for too long however as the cartridge is light sensitive and exposure to light for long periods will ruin the cartridge. (13 seconds for direct sunlight and 10minutes for flourescent or led, do not use a krypton or incandescent light to examine any unit)As the unit powers up the fuser rollers will spin allowing you to see the surface of the teflon sleave.Again this is VERY fragile, do not touch prod, poke or otherwise stick anything into the rear cavity of this model as damage will almost certainly occur.In truth I have to lean strongly on the chances you simply have a bad cartridge. Although "cleaning" once in a very long while resolves some issues, usually it's the most common jumped to but least likely solution.
