Question about HP LaserJet 4 plus Printer

HP Laserjet 4 Plus

I've had this printer trouble-free for years.  I recently had to move it because my floors were being sanded and polished.  When I went to use it the paper jams and when I open it at the back it is all "fanned up".  the printer message is of course "paper jam".  Any hints as to how to fix this?


Many thanks

Did you check to see if any foreign objects are in where the paper goes, I used to get that with my canon printer and I thought it was broken then I found a little rolled up hershey kiss wrapper down there when I put my hand in






check the instructions , check the computer to find the printer problems or to use HP tech support chat to find the problem becasue your printer is from HP good luck if it is defective or problem then replace new one for if under warrantly ok







Probably the wrong paper - try a different weight, less than the one that is jamming. And do not use a cheap paper, it is not worth it - it shoals off a lot of paper dust which will also cause a jam on your machine. (And make you sneeze!).






May be somthing is obstructing the paer sensor.

Download driver windows vista

There is no downloadable driver for the HP Laserjet 4 series of printers as they are built into Windows starting with Windows XP. The driver that you should select can be either the Laserjet 4 or 4 Plus as they are both the same printer. (What made the 4 into a 4 Plus was the addition of the Jet Direct card that allowed attachment to an Ethernet network.)

I have an envelope feeder that came with my old LaserJet 4 many years ago. I replaced the LJ 4 with an LJ 4-Plus and tried to use the envelope feeder on it. I get an immediate error message "EE...

My suspiction is there is a tab on the tray that triggers a switch telling the printer what type of tray has been inserted. Your old tray is likely different from the Plus 4 tray and the printer knows it.

This is for a HP Laser Jet 4. I have had it for years and it has worked well. Now on an erratic basis, paper gets hung up sometimes only partially coming through (with wrinkles at the end) other times it...

Symptoms: Your HP LaserJet 4/4M is constantly jamming at the back of the printer. Sometimes the paper is folded like an accordion. Other times the paper has a big curl on the bottom

I have an HP laserjet 4 printer and suddenly it just turned off.

If it won't turn on, the power supply is dead. Time to bury it, I'm sorry to say.

57 (or 57.1) SERVICE Message (Main Motor
The 57 SERVICE indicates that the DC Controller PCA detected a
general motor failure. The Main Motor drives all moving
components in the printing process. The Main Motor is a 4-phase,
DC servo motor controlled by the DC Controller PCA.
The formatter detects a Main Motor failure when:
• The Main Motor does not come up to speed within one second
of receiving drive voltage.
• The Main Motor deviates from the correct speed for one second
after reaching the correct speed.
Main Motor Functional Checks
• Inspect the gear train for debris that would block the free
operation of the gears.
• Check the gears in the Toner Cartridge for wear and binding.
• Reseat J211 (or J214 on the HP LaserJet 4 Plus/4M Plus) on
the DC Controller PCA, and the main connector on the Main
Motor Assembly. Refer to Figures 7-16 and 7-17 for the DC
Controller PCA connector locations.
• If the problem persists, check that the +24B Voltage is present
on the DC Controller. If the voltage is not present, replace the
DC Controller. If the voltage is present, and the motor does
not rotate, replace the Main Motor Assembly
