20 Most Recent HP LaserJet 4si Printer Questions & Answers

This most often caused by a postscript error or insufficient memory in the printer.
You could try too see what happens if you instruct acrobat reader to print as image.
This setting is usually found in the printer selection screen under advanced options.
Note this setting is available for windows, for apple I'm not sure this option exists.

Your post is correct that error 53 refers to bad memory board or at times defective SIMM only. Since you have replaced them and no change, you may want to try to do a Cold Reset of the printer. This is done by powering on the printer while holding down the GO or Online button. Additionally, you may want to check/reset your NVRAM settings which can be done manually through the Service Mode.

This page lists most of the HP Laser Printer error codes. This link displays most HP LaserJets - Cold Reset Instructions.

Hope this be of some help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Trouble with the HP Laserjet printed output may be solved by using the following settings (or similarly named ones): "Use raster Graphics" (instead of "Use vector graphics"). This may fix the problem of "reversed" text (white on black background) not printing, as well as other problems. "Download TrueType Fonts as bitmap soft fonts" (select "bitmap" instead of "outline" or "graphics"). This may remove the overlapping of text on the printed document. "Graphics dithering" select "coarse" or "fine" (instead of "none"). This selection may improve the quality of images contained in the document. You can find all these settings in your printer properties. Go to File, Print, click Preferences, in Printing Preferences, click one by one all the top options, and change one of the top solutions, one at the time, checking your printing output. Always check if you have the latest version of Adobe Reader Program. If not download the latest version from Adobe, it's free. Is this the first time that you have the problem? or with the same printer (HP 4si), did you were able to print PDF files in the past?

Hi, When I've worked on printers with this problem in the past it usually comes from the high voltage power supply going bad. There is also a low voltage power supply that runs everything except the actual printing so your printer will still operate without any errors but the print quality will go bad. The high voltage power supply is located under the bottom of the printer and it's too hard to replace. I can't advertise for any place on this site, but if you type in the part that you need into a search engine and look for parts on everyone's favorite bidding web site you should find the parts you need. Good luck.

Seems the wifi controller in the printer is fried. This worked for me.
Power on
Press Home button repeatedly while the unit is powering up.
When the menu appears hit these items quickly
1. Wireless Menu Icon (wifi icon)
2. Wireless Menu Button
3. Turn Wireless On/Off Button
4. Off Button

You have about 2.5 seconds to do this so it likely will take a few tries. When you have successfully disabled the wifi, the printer menues will work and the initializing sequence will finally complete.

You will have to hardwire the printer to an ethernet network or use some sort of wifi to ethernet adapter if you want to print over the network but the printer still works.

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?
