Question about Dell 3000cn Color Laser Printer

Paper transport does not work; terrible grinding noise

Hi, recently my Dell 3000cn printer suddenly stopped picking up paper to run through the printing mechanism. Instead it makes a very loud grinding noise and gives a paper jam error message, telling me to open the Reg cover (inner rear cover). The first time this happened there was a jam, but after removing the jammed paper I kept getting the same grinding noise and no activity in the paper tray. After a few hours on the phone with Dell tech support, they told me to replace the "vertical transport assembly," which I did, to no avail (same grinding noise, still no paper being picked up from the tray). What could this be?

    Same problem, also the Reg cover is difficult to close (no obstructions visible)

    Exactly the same problem. Seemed to start without any intervention. A paper jam is reported but there is no sign of a paper jam. Paper does not seem to feed from the paper tray. I suspect something is stuck somewhere.

    Paper jam error message and grinding noise.

    Exactly the same problem - it went away once but came back agin.. I suspect some rolelr or spring is out of place or worn - anybody now which one and where?

    Exactly the same problem. I finally got sufficiently fed up with the problem so I tried a couple things... just opened the back cover and found three little photo-eye looking thingys that had lots of dust on them. One in the center, and one on each side. Hosed them off with a can of air, and... so far it has not "jammed". I am only about 30 pages into it, but that is 28 in a row more than I could do previously.

    Same thing - grinding noise, I cannot see what is wrong with it and I am getting really frustrated with it.

    Can you provide some details on what you took apart from the back and put together - I have opened and removed all the removable parts (with blue handles or pulls) and put them together to no avail. Did you actually unscrew something?

I took mine apart from the back and put it back together and it worked. It is probably due to moving it and the bottom paper tray alignment gets out of whack. I inspected all of the gear train and didn't find any worn or missing teeth. I suspect a paper jam started it and the user turned the printer around to open the back door. Since the handles are on the printer the tray doesn't move with it which allows it to separate and possibly jam a pickup drive gear.

My Dell 2135cn printer all the sudden started making crazy loud grinding noises. Then I got a paper jam. I fixed the paper jam and tried to print again, but got the loud grinding noises and paper jam...

Refer to the service manual in disassembling the device.. Clean it thoroughly then try it again.. If, you have no experience in doing so, hire a qualified tech to do so.

Printing tray is seem to not grabbing papers. when trying to print, it makes a lot of noise.

From your description there are two issues, the first is the papers in the tray are not been picked up, second! it is very noisy when attempting a print job. The gears are mostly plastic and have worn to the point that papers can no be scooped up, and finally the noise confirms ware and tare on the system. The cost to repair will be high! this is where a personal choice will need to be made weather to fix or replace, if you use it constantly then I would recommend a replacement.

Paper not loading and getting jammed

. There are rollers that cling on to the paper and move it through the machine. When the rollers are worn down they do not grip the paper. For a short fix you can get something rough like sandpaper, brillo pad, etc, and gently scratch the rollers to give them some traction. This will temporarily solve your problem until you can get the rollers replaced.

Paper not feeding

The Dell 3000cn & 3010CN both display this fault.

The root cause of the problem is the Rubber pads of the feed roller in the paper tray become warn and fail to grip the paper the paper feeds a few millimetres and then is let go by the worn roller, the paper path sensors pick this up and then a paper jam is notified.

The only remedy for this problem is to obtain a new feed roller for the paper tray mechanism. Unfortunately dell in the UK do not sell maintenance kits to the public, and therefor ehte only place I found them wa on Ebay in the USA.

The kit in quetsion is the vertical paper feed maintenance kit. it costs around $50 plus shipping.

The only other option is to have a Dell approved service agent replace the rollers for you.

If you hear a grinding or cruching noise when paper is fed, then one of the mini plastic guide rollers had detached itself from its position and wound up in the tape path mechanism (very expensive repair)
