HP LASER 4350 MAKING NOISE IN BACK WHEN PRINTING    

Q:  We have an hp laser 4350 making noises that seems to be coming from the back of the printer.  The printer sound is like a grinding, rough sounding noise.  Has anyone heard of this

A:  hp laser 4350 making a grinding noise is a very common problem with these printers.  There are two parts in play that contribute to this noise; 4350 fuser assembly and 4350 swing plate assembly.  The hp laser 4350 swing plate assembly engages the fuser assembly via the black gear and drives the fuser assembly.  When the gears that are interconnected between the two become worn you will commonly experience the noise that is being described.  Simply replace the fuser assembly and swing plate assembly and the printer will sound like it did out of the box

HP LASERJET 4350 PRINTING SLOW FROM TRAY 2       

Q:  I have an hp 4350 that when printing from the cassette tray 2 does so at roughly half of its normal page speed.  These are simple small Microsoft word documents, so I don’t think it is any sort of a memory (Ram) issue.  Any thoughts?

A:  If the media being used is a high fuser mode type then the printer speed will slow to about half and create conditions that are being described.  Check the paper type in the tray 2 to make sure it correlates with the media that is loaded in the tray.  Sometimes custom paper sizes can also cause the printing speed on an hp laser 4350 to slow.  Check that the paper size is set to a definite point as well as that the custom paper size is not selected on the paper tray.  If all the above check out, try replacing the paper tray, then possibly the sensors in the base of the printer.

HP LASERJET 4350 NOT DETECTED ON THE NETWORK

Q;   I have an hp 4350 that suddenly stopped printing and fell off the network.  Everything was working fine and then print jobs started to get stuck in the print que.  After the jobs started to time out and fail I tried to log in via the web jet admin but the web just timed out.  I then proceeded to ping the printer which also failed.  Any ideas

A:  First check the IP settings of the printer by printing out a configuration page. Check to make sure all settings are set as they should.  Sometimes when you try printing out a configuration page the printer will not print the IP configuration page.  This can happen for a couple reasons.  The first is that the embedded NIC card has been disabled,  there is not enough memory installed, or finally that the network card has gone bad.  First make sure there is at least 80mb of ram, enable the NIC if its not and finally if all else fails replace the main formatter board. 

 

HP LASERJET 4350 PERFORM PRINTER MAINTENANCE:

Q:  I have an hp laser 4350 perform printer maintenance message on my display.  The printer has been running well and is still running as is should be since the message has been on.  Is there something that I need to do to my printer or can we just clear the perform maintenance message and continue on.

A:  The perform printer maintenance message on a hp laserjet 4350 simply means the printer is due for its replacement rollers and fuser.  Every 200,000 pages printed the printer will prompt this message and it is recommended that all the rollers and fuser assembly be replaced.  It is in my experience that the rollers and fuser assembly wear out well before the 200,000 page count, so replacing maintenance kits before that point is very common.  The hp 4350 maintenance kits come with instructions with how to reset the page count and clear the perform printer maintenance message.

HP LASERJET 4350 TRAY 2 CASSETTE DOES NOT OPEN

Q:  We have an hp laserjet 4350 printer with a tray 2 cassette that is not opening when we try to load paper.  What would cause the 4350 paper tray to get stuck?

A:  There is a small door which gives access to the separation roller in the tray 2.  That door is governed by a small spring which keeps that door from lifting up and getting caught on the inside of the printer.  I would be willing to bet that door is missing the spring for whatever reason and now the door is getting hung up when you try to open the tray.  Try going to the back of the printer and adjusting the front of the tray from there.  That should get the tray un stuck for you.  I would recommend replacing the paper tray once you got it out.
