Tip & How-To about HP LaserJet 4350dtn Printer

HP LaserJet LJ 4350 locks up when duplexing

Symptom: Your LaserJet 4350 prints just fine until you try to print a double-sided page. Then you see the page start to exit, pull back in, then stop. The Data light continues flashing green, and the display reads, "Processing..." There is no error indication, but the machine won't print the second side and continues to hold the half-printed paper in the duplexer. If you open the top cover and close it again, the printer will eject the page, then try to print the whole thing again, unless you're quick enough to cancel the job first.

Cause: The printer is expecting a different sized paper than what it's running. Often it's not the menu settings, but a little lever in the paper tray itself. Pull out the paper tray you're trying to print from and look for a little blue lever on top of its right-hand side. The lever is labeled "Standard/Custom." Flip it to Standard (parallel to the tray side) and your problem should go away.

According to the specs, this printer does not have a duplex unit and therefore cannot print double sided prints.
DOUBLE SIDED PRINTING USING A SINGLE SIDED PRINTER
If your printer does not have a duplex unit then the printercannot print double sided pages automatically.
You can print double sided pages but you have to do it one page at a time.
First print Page 1 then place the page back into the paper tray, but turn thepage upside down and the print Page 2.
Then print page 3 on one side then page 4 on the other side and repeat for therest of the document.
I suggest you try a test page first, to get the printing the right way up onboth sides of the page so it reads correctly.

My HP Laserjet 4350 is printing 3 copies all the time even the test page.


Press the green button (with the "check" sign on it), then press the "down" arrow button four times.
The display should read "configure device".
Press the green button again.
Press the down arrow one time? until you see "printing".
Press the green button.
Scroll down to "copies"... it probably reads "3".
Set it back to "1" and then press the green arrow button.
