We just changed the drum and cartridge on our HP9500. The prints now have about a 2" strip of black toner along the edge. What should we do? It now says replace cleaning cartridge, could that be our problem?

You have a defective cartridge.

Sounds like the end seals in the cartridge are bad. Remove the cartridge and see if there is toner built un inside printer. Also look at the drum on the cartridge to see if it has black lines that line up with the pirnt defect you are seeing. Try a new toner cartridge and run about 50 pages through.

I think you should contact the manufacturer or vendor who sold you the cartridge. The standard warranty is 90 days. I believe that it will prove to be a bad toner/ drum (which are the same thing for this printer.)
Besides that you can do a "half-test". Stop the print job half way by opening a cover during the print process, before it is transfer to the paper and fused. Look at the drum or transfer belt and see whether the defect exists early in the print process.
There may also be a contact problem with the black toner. Check for bent metal on the toner, or chassis that should mate and conduct charge to the toner.

Hi there,

This problem is often caused by spilled toner. Open the printer, carefully remove the cartridge, and give it a few bursts of compressed air. Often running several pages or type through will also fix this. If it persists, replace the toner cartridge.

Hope this initial info/idea helps. Let me know for any clarifications.

90% of the time this is your toner cartridge. Remove cartridge. Turn it over and slide open the protect plate. You will probably see the same "dark edge" of toner on the drum. You can verify by changing the cartridge. Even if you have an old one laying around you can shake up and try to see if the edge goes away.

The following table should help

Contamination in the laser path - 1. Clean the laser path. (Remove the laser/scanner assembly and clean the lens.) 2. Replace the laser/scanner assembly

Defective fuser - Replace the fuser assembly.

Lack of toner or faulty toner cartridge - Redistribute the toner in the toner cartridge. If the problem continues, replace the toner cartridge.

Dirty Corona Wire - Clean the Corona Wire.

Defective Drum - Mostly applies to B&W printers. Clean the drum or replace the drum.

The fact that it's printing anything suggests that it is not a Toner problem. Remove the toner, and have a look at the run inside the printer, checking for any excess toner which is in there. Also, check the Drum and Imaging Unit for damage, wear and tear etc. There will also be a static strip near the imager, with a little tab which you can sweep across the unit to clean it.

Its probably a defective toner. If the film on the toner drum is scratched it can cause toner to stick to the drum everytime it spins causing the constant marks.

Check your Drum cartridge, if you see your strip replace it....If it's not the problem you may have a bad Fuser ....

check the cartridge model ,unsinstall tha black then refill to refilling station.2.purchase new cartridge black only
