Dell 3010cn: error 004-321 reseat drum

[Xenon136]

Someone gave me a Dell color laser printer (3010cn), supposedly because it wouldn't work with Windows 10. When I set it up, it seemed to be working (it printed 1 test page just fine).

The next time I tried to use it, it diagnosed itself with error 004-321 and demanded that I "restart printer reseat drum contact support."

I followed this guide as closely as I could: http://www.dell.com/support/article/us/en/19/SLN153697

It boils down to reseating the drum, cleaning some belts and sensors, and if that doesn't work:

• Run the IBT rotation sensor diagnostic
• Remove the drum and run the photoreceptor motor diagnostic
• Replace the drum and run the photoreceptor motor diagnostic

The printer passed all 3 diagnostics but still gives the same error. The troubleshooting guide says I should now contact support, but Dell doesn't support this model.

Do you need a color printer?
If Dell does not support it, there is little reason to keep it.

For occasional use, a low-cost trinket printer is cost-effective. In theory, the laser printer is better for huge production printing. But major repairs on the l laser printer becomes very expensive. And you don't even know if it can be repaired.

The drum isn't obviously damaged, how would I tell? I took some pictures:

I'm also not sure if I identified the belt and sensor mentioned in the thread correctly (as in the first image).

Some people reported that adjusting a belt, cleaning a sensor, or realigning a film reel helped, but I wasn't completely sure what they were talking about. Especially the film reel. (Note that the thread was about the 3100cn not 3010.)

From the Dell Forums...

The 3100 is basically the same printer with 3 major differences:
1. it has a second paper drawer below the MFT, which is NOT OPTIONAL,
it MUST be attached or the 3100 will not print.
2. it has a built in ethernet port to be used as a stand-alone network printer
(however since you can't change paper sizes without making changes to both
the printer drivers and AT THE PRINTER ITSELF, this is somewhat less useful.
3. the 3100cn comes with and uses full filled 4000 page toner carts, the 3000 uses
carts that are rated for 2500 pages, essentially they are half filled carts with
Dell making just enuf of a physical change to block 3000 users from using full filled carts.
