I have an HP PSC 1310 series All-in-One printer. Only recently, I installed a blank ink cartridge, and now the printing down the middle of the page is blurry. It almost looks like the printer is adding a shadow to the text in the center. I've tried re-aligning the cartridges, but the problem remained. Can this be fixed without getting a new ink cartridge? Is that my only solution?

The most likely cause is ink buildup on the encoder strip. The web page HP had on this subject has been removed, but said something like the following:
HP Deskjet, HP Business Inkjet, and HP Color Inkjet Printers - Cleaning the Encoder Strip for Vertical Flaws in Print, Margin Offsets, or "Stair Stepped" Margins
The encoder strip is the semi-clear strip located just behind the carriage rod. Its purpose is to help the print cartridge accurately keep track of its position as it moves along the carriage rod. Sometimes dust, ink, or oil can accumulate on this strip and cause the following problems:
Clean the encoder strip inside the printer by following the steps below:

I followed the steps provided in cleaning the encoder strip and I still have the problem. lst few pages printed fine then started blurring above and below the printed line......very black but doesn't rub off! I've taken the cartridges out and cleaned them. I recently put in a new black cartridge, could I have a bad cartridge or has my printer gone caput? I NEED this printer TODAY. I'm running statements for my husbands business.

Dude.... I just wanted to personally thank you for your post! I've just spent the last 3 hours trying everything in the book to fix my phantom ghostly paper jam..... I was just about to throw the dam printer out the window and then you saved him from going flying..... Or maybe from a hammer slamming into him!!! Anyway, I just spent a few moments to register here just so I could personally thank you, so "THANK YOU"
