Hello,
by the description I would say that you have fixing problems. Maybe the pressure is not right between fixing rollers or the fixing roller is worn out. However, call service!

Imaging drum reach 20,000 (black only) or 5,000 (color), replace the image drum.

Supplies life
The life of the imaging drum depends on the number of black-only or color pages that print jobs
require. Imaging-drum life is also affected each time the device calibrates because calibrating causes the imaging drum to rotate. Imaging-drum life is measured in terms of number of rotations rather than number of pages printed.
The type and length of print jobs also affects drum life. A series of short print jobs uses more drum
life than an equivalent number of pages printed in a single large job. To extend drum life, print
multiple copies of a print job at one time rather than sending the same job to the device multiple times.
The life of a print cartridge depends on the amount of toner that print jobs require. When printing text at 5% coverage, black print cartridges last an average of 5,000 pages and cyan, magenta, and
yellow print cartridges last an average of 2,000 pages. High-capacity cyan, magenta, and yellow print cartridges last an average of 4,000 pages. (A typical business letter has 5% coverage.)

You need a supply of ink in both cartridges in order to print. Even if you are only printing black ink and there is a black ink cartridge with ink in it, your printer will not print without the color catridge installed and it has to have a supply of ink in it. I wish I had better news for you, but unfortunately I don't.

This is most likely the paper pickup or registration solenoid sticking open.you can remove the solenoid, clean the mating surfaces and install a dampener, (we use a small strip of cloth tape) if one is starting to stick I would do the carousel solenoid (at the top of the machine near the laser scanner) at the same time to avoid a second problem

Contact HP, they have a warranty on the toner

Put a new black toner cartridge (CC530A) in your printer.

The low ink could definitely be the problem thats prompting the error. To begin troubleshooting print the supply status page and confirm the state of the various supplies. Follow the steps below:

Software and driver downloads for that model can be found at HP's website, here

The error refers to a parallel printer cable, also known as a centronics cable. This surprises me as I believe this printer is connected via USB cable. If not, get a new parallel cable and try it. Here's a link about that cable...
http://en.wikipedia.org/wiki/IEEE_1284

If it's USB, I would use HP's online chat and ask them what to do about the problem. You can reach them here...http://h20000.www2.hp.com/bizsupport/TechSupport/SupportTaskIndex.jsp?lang=en&cc=us&prodTypeId=18972&prodSeriesId=445194&taskId=110

Hi

No print on the left side indicates that the toner powder on the left side is almost empty. Try to remove the toner cartridge and shake it well if the toner are new.

If still the same, you need to replace new toner cartridge to get better print out.

Please rate and make a comment if you find this solution very helpful and might help others as well. Post more comments if you need more help.
