Catridge block - HP OfficeJet Pro 1170c InkJet Printer

The issue you have described regarding your printer is mainly due some dirt on the printer drum, As most of the issues like this get solved when you clean the Drum, However before you start troubleshooting your printer you should try few steps to check where actually the issue lies is it the Drum or the cartridge or is it with the driver software or even with the document file software program that you are trying to print form, so try these steps below to know where the issue lies here is what you need to do,


Try to scan and print a document, by using the copy option on the printer control panel directly (Check if the print is good, if so then the issue is with either the printer driver or the document software you are trying to print).


If you find that the print output is the same which means the printer again printed a complete black page try to clean the Drum of the printer with a soft dry cloth. Please make sure that you completely disconnect the printer power cord and leave the printer powered off for sometime before you remove the printer cartridge
and clean the Drum.


Alternately you can also try the old cartridge if you still have it with you just to check if the print out is fine with it, with this we can isolate the issue as we will come to know that the Toner cartridge is gone bad and you can then replace it.


However if you find the copy was fine then you can try printing a test page and check if its good. (If you find that if the test page prints okay, then try printing any other document form a different program however if you find that the test page looks like the same I mean if it is completely black then you can try to uninstall the driver and reinstall it again).


Here is how you can uninstall the driver and reinstall it.

1. Click on start, point to control panel and click on control panel.
   
   
2. Click on Add/Remove icon and select the printer driver and click o remove.
   
   
3. After the un-installation wizard is complete close all the windows and disconnect the printer form the computer.
   
   
4. Insert the driver disk in the Disk drive and install the driver.
