We are using the photosmart 8750 to print X-Rays at a dental office. Every first print in a couple hours for the big prints comes out very jagged and faded. The smaller ones print out great all the time. We have to clean the cartridges a couple times through out the day just to keep the printing clear. I swapped out all the inks for brand new ones and that helped a little, but we just had the problem again with the brand new inks. I have been troubleshooting the problem but cannot find a solution. It prints perfect except for a few per day that come out very poor. I have gone on and looked at all the advanced printer settings and everything looks right. Any help would be appreciated. Thanks!
I can see that some of the time when printing your x-rays that the print quality is poor. I would be happy to provide some suggestions that may resolve the issue! Are you printing on transparent paper, photo paper or plain paper?
I recommended ensuring the printer is getting full power at all times. It is recommended to have the printer plugged into the wall directly and not a power surge protector. This may sounds silly but it is a good way to ensure power is not a factor and may eliminate unnecessary troubleshooting.
If your still experiencing the issue I would suggests cleaning the copper contacts on the HP Cartridges and in the HP printer. It is explained in the previous document but I can provide a more specific one here: Cleaning the Contacts.
Please post back and let me know how it goes!
