The Density Sensor is located inside the right upper door and senses the colour calibration pattern for each colour formed on the transfer drum during a calibration cycle. Press GO. Print a configuration page and then troubleshoot as an Image-quality problem as instructed in the user manual. Check the transfer guide for cracks and replace if necessary. Check the event log for errors numbered 54.00.0<X> the X indicates, 5-sensor abnormality, 4-Cyan, 3-Magenta, 2-Yellow, 1-Black. The last 3 error codes should be seen on the Configuration page.

Density sensor out of range

The density sensor is located in what is called the Colour Registration Detection Assy. When you open the front door where the ETB belt is, the assembly sits were the door closes at the top on the printer side.

It can get toner on it, so check it and give it a clean. But do not touch it with your fingers.

Hp 3500 faint printing and colours wrong

Well, first off, are you using OEM or compatible cartridges? Compatibles are OK, just as long as they weren't rebuilt just by refilling. Secondly, you may want to check in the "Print Quailty" menu; here you will find info on increasing and decreasing the print density. Do you observe light printing over the entire page or just ceratin areas? How about certain colors? More to follow...............

HP LaserJet 3550 spits out blank paper when job sent from computer but prints fine when printing directly from printer

Try connecting the printer via the USB port on either one of the computers. Then test if the machine prints fine then likely possibility is that the Network interface card is faulty remove the network card and install in a different slot and test. If the same thing happens then reinstall the drivers and test.

Hope this helps
Thanks J

Paper jam

If you have pulled out paper that was stuck before you may have flipped a sensor flag out of position. I have found in the past small pieces of paper left under the plate at the very bottom of the toner catridges where the paper comes in.
