My HP laser jet 3500 color printer documents look horrible

Maybe you have installed a different standard printer. Right-click on HP 1515N and select Standard printer

Best bet ->HP Support & Drivers

Your cartridges are bad. Whatever colors are causing problems need to be replaced to fix the problem

Faded prints are possible due to following reasons.

1. Fogged red mirrors inside the Laser box
2. Alignment of the Laser Box
3. Calibration Problem
4. Cleaning Problem

I will guide you with simple steps first, if this dosen't work working with laser box is little tough & time consuming, hence will describe later.

To Calibrate the colors, Press the 'Green Button' in the front panel, use the arrow keys to navigate through menu.

Select 'System Setting' by pressing the green button again, navigate using the arrow keys and select the 'Calibrate Color', select green button to select and confirm to 'Calibrate Now'. This will take few minutes.

In addition to that, to clean the paper path, select the green button and use the arrow keys and navigate thru' menu and select 'Service'. select using the green button and navigate through menu and select cleaning option. This will take few minutes.

Try printing some documents and check whether you have fixed. If you have not got the original print quality, Let know to guide you more technically.

Hello Friend,

First of all please check for correct drivers for printer.

Secondally : Please draw three different - different color boxes in word and print them on you printer and find out which one color is missing. Example as follows.

check the paper size in the printer driver settings.
this should also be set to letter.

The ink of your printer seems to be empty. Replace the toner cartriage to solve the problem.

Pull out the fuser at the rear of the machine.

Do you use original genuine cartridges or refilled ones. It sounds like you have had a leak and need to completely clean out your printer heads, rollers and perhaps do a deep claean as well. You can buy faulty cartridges and toners that have one leak, then the ink continually leaves traces as it prints. When you say callibrated, do you mean you ran print tests and setting tests. Running a print test can often help to diagnose ink issues an d narrow the results down a bit. After a thorough clean, you could try uninstalling and reinstalling unit.
