Erro with printing using the lower try

That's a "beam detect error"
Could be bad laser/scanner or DC controller.

It's an old printer. It might cost you more to repair it than to replace it.
Let it go out with dignity.

did you peel off the tape from the cartridge before installing it ?

when you want to print something, don't press the print button, select print review and selkect properties, make sure its not printing DRAFT --select fine

have you tried the print test

Depends on the weight (thickness) of the card. Assuming it's not too thick, feed it in through the manual tray (the flip-down tray on the front).

Give this site a try....hope it helps.

My sentiments exactly...although you may try shaking it vigorously left to right 5 times, then up and down twice. This sequence has proven extremely effective for me.

MP LOAD,
PC LOAD, or
LC LOAD
paper size,or
envelope size
The printer received a request for a paper or
envelope size not available in the printer.
MP LOAD: Load MP Tray with the requested
media. If the size is not selected in the printer
control panel, use the [MP[Paper[Size] key to enter
the requested size, or press [Shift] + [Continue] to
draw the requested size from another source, if
available.
Note: If MP LOAD remains in the display, you may
have to clear the buffer by resetting the printer.
Press [Shift] + [Reset].

Go to Start > printers and faxes> right click on the laserjet4 icon>
properties > click on printing preferences on the first page > click advance on the next page > under Graphics, you will see print quality. Change it to either 600x600 or 1200x1200. The higher the number, the darker the print.
If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

Dirty Primary Charge roller. Change the Toner Cartridge.
Bad Toner Cartridge. Replace the Toner Cartridge.

These do run slow 4 pages a minute, they were fast in their day.
Check driver settings on pc that paper type is set as normal paper.

Otherwise it is the paper having high moisture content or machine needs a new "baker" aka the fuser assembly rendering it unecomical for repair (lower orange roller will be creased or upper roller losing its coating)

In the printer driver, make sure you have the paper sizes set correctly  etc. Go over all the basics first.

Make sure that the options set under the "Device Settings" and "Advanced" tabs are relevant to your media and page sizes.

The chances are a setting in the driver has been changed by mistake.
