HP Color LaserJet 4730xs MFP Printer - Answered Questions & Fixed issues


First thing to try is this, please go to control panel on the printer and to aministration menu. Scroll down to troubleshooting and find the PQ troubleshooting option and press ok. This will print a series of test prints. If these prints look OK then likely you have an issue with your driver. If they are faded, the second thing you need to do is check to make sure that your firmware revision is current. On the config page that prints with the pages just printed above, look on the upper left for firmware revision. Current version is 46.300.0. Download from here and install following the instruction in the readme file. Did it print OK before changing cartridges? If you installed remanufactured or 3rd party cartridges, the toner will not always provide the same quality of print.

Logic says replace the black cartridge...AGAIN!! However, you can put the machine in 'disable cartridge check' mode which is found in the diagnostics menu. This will allow you to remove/interchange cartridges to help identify problem cartridges. Most importantly this will allow you to identify whether you have a black cartridge slot problem which makes it a machine problem or whether you just have a bad cartridge. First thing I would do is run the machine without the black cartridge and see if noise disappears. Good luck!!

Juliet. Most likely the scanner lamp, or scanner control unit assembly is defective. If you're technically savvy, you could remove the scan glass and lube the shaft that the scan lamp assy slides on. Sometimes that will fix it. Otherwise, the whole top scan unit will need replacing. That could cost over $300 for the replacement.

Is it all the colors? Make sure the drum shutters open and close when opening and closing the front door. Missing magenta color is common in this machine and other machines like it. The magenta laser scanner mirror sits in the lower part of the printer and face up and toward the front of the printer. Loose toner from printing tends to settle on this mirror. Over time the mirror coats over and the actual laser scanner beam cannot reflect off the mirror with proper intensity, usually resulting in very faded magenta color or no magenta at all. Good luck

Transfer Belt Error Error code 59.FO. Replace the belt.

Don't confuse with 59.CO which is a machine problem, usually related to develop disengagement assembly. If someone has previously worked on it, then all it may need is a main assembly removal and replacement, with replacement being done to HP specs. (gear alignment and so on)

the squeal may be due to the fact that the paper tray won't lift...the lift tray should give just a bit. make sure there is not something under the tray where it won't go down. and if it doesn't go down, then the pickup roller can't rotate, and you get the noise. best answer with info. given

Check your toner cartridge first.
There is more than one cause for this problem. It could also be your transfer roller that needs to be replaced.
Or it could be the scanner that has gone out.
Are you getting an error code?

Go into the settings. You don't say what kind it is so I can't tell you where to go to do it.
