Blotchy printing output for HP 8550

We just picked up a used HP 8550 and the print quality looks like it has a tie dye effect. Do we need to replace a part?

This is often caused by the TRANSFER DRUM having deteriorated and become 'bumpy, or 'dimpled' - take you pick depending on how YOURS looks. This causes incomplete contact with the Photo-conductor drum, and as a result doesn't lift all the image off it.

The only solution is to fit a replacement TRANSFER KIT.

I have also seen NEW 'old stock' transfer drums, straight out of the box like this, so its obviously an 'aging problem' with that component.

Also seen it in a very low count printer that was in storage, unused for over 3 years.

SOURCE: Pale print on PDF files

It sounds like a driver problem. Try replacing the driver for this printer on the printers folder, using the HP LaserJet Series II. With this driver, try again the PDF file and see if it prints correctly.

SOURCE: print head failures HP 1050c

the tube system has an air leak causing a dryfire situation. air + printheads = damaged printheads. most users replace the black printhead more often than the colors. the seal where the printhead feed pin fits into the carriage is the end of the tube system. the hole in the seal becomes to large and doesn't properly seal the air out. order the tube system. complete and concise instructions are included in the box for tube replacement. this is considered an end user replaceable part. good luck! please rate this!

SOURCE: HP OfficeJet 6110 Prints very slow then aborts about 1/3rd way through print

I identified this issue with my Officejet 6110xi All-in-One as firmware corruption. Attempting to install the supplied firmware update gave the error that "no hp device connected to the computer would benefit from it at this time." Attempted to power down the printer using #9 keystroke and got "FULL RESET" message, but problem of extremely slow printing and erratic behavior of the print heads persisted. I solved the problem by putting the printer outside in cold weather for two (2) days. This frequently resets firmwares with software corruption back to their embedded EEPROM state. Hooked the printer back up and worked fine. If cold weather is not available you could try other creative methods of cooling the device, just use a plastic bag and with ideally some drying packets thrown in to prevent excessive moisture buildup in the cold environment. The colder it is the faster the firmware resets.

Xerox Phaser 8550 having color quality issue


If you are using third party ink sticks contact the manufacture and they will, if you use enough of thier product, send you a new print head and send out a tech to change it. Media Science is the most likely source of third party ink.
You can also switch to Xerox ink sticks and the colors will be correct after several purges to get rid of the old ink.

Can't figure out how to adjust darkness/tone for printer output


Hi,
Below you can see a step by step procedure on how to change the print quality of your work....you need to make test printouts in order for you to see the results....at the end there is a link to the manual for your printer...GOOD LUCK!!!

Print-quality settings affect print resolution and toner usage.
Use the following procedure to change print-quality settings:
1. Open the printer Properties (or Printing Preferences in Windows 2000 and XP).
2. On the Paper/Quality tab or the Finishing tab (the Paper Type/Quality tab for some Mac drivers),
select the print quality setting you want to use. The following options are available:
● 1200 dpi: This setting uses ProRes 1200 to provide fine-line detail at 1200 x 1200 dpi.
● 1200 dpi effective output quality: This setting provides 1200 dpi effective output quality
using FastRes 1200.
● 600 dpi: This setting provides 600 x 600 dpi output with Resolution Enhancement technology
(REt) for improved text.
● EconoMode: Text is printed using less toner. This setting is useful when you are printing
drafts. You can turn on this option independently of other print-quality settings.

Blotchy prints


First, make sure your print cartridges are aligned by going to your printer software and printing out an alignment page. Secondly, adjust your printer software/properties to make sure your printing to your best photo quality. Third and most important, make sure you have the right kind of printer paper, which is probably the main reason that your page is blotchy.


Another reason its blotchy would be if the printer was not a good one.
