print quality

[jer-bear12]

Pages print in a sepia color only, have installed new HP cartridges , went through all the trouble shooting options, IE cleaned the heads, etc and nothing corrects the problem ,  at times it will start to print a few lines in black then reverts to the sepia color.. Have spent enough on cartridges to buy a new printer!! not sure what to do next..any input appreciated..

A very warm welcome to the HP community. A very good day to you. 

I understand that you have an HP 8100 printer and are facing print quality issues. I read that the pages print in sepia color only. You have installed new cartridges, cleaned the printhead and issue still persists. Fabulous analysis. Spectacular diagnosis of the issue before posting. Kudos to you for that.

To provide an accurate resolution, I need a few more details: 

• We have other printers from the laserjet and Photosmart series that fall under the HP 8100 printer series, But I support you're referring to an HP Officejet Pro 8100. Is that correct? If not then please let me know the exact product model no. This link will help you to find the model no: http://hp.care/2bygf7l
• How is the print quality when you make a copy?

Meanwhile, I did some research and suggest you to perform the following steps:

• Disconnect the power cable from the printer while the printer is still ON.
• Disconnect any other cables if connected the printer.
• Press and hold the printer’s power button for 15 seconds.
• The printer should be directly connected to the wall outlet and not to a surge protector. Reconnect the power cable to print and the printer should power ON by itself. If the printer doesn’t power ON then please manually power it ON.

If the issue persists then it looks like a printhead issue. I suggest you to refer to the "Solution five" from this link. 

I hope this information helps. Keep me posted. Cheers! 🙂
