MX-M5050 print quality

[bigdaddyooo]

I have 4 machines here all doing the same thing where all prints have a "screen door" look to them. EVERYTHING is new. Drum, Dv, TU and MK. all calibrated. Here is a photo so you can see the phenomenon I am getting. I am leaning toward a new DV unit. OBTW, it has 70k on the machine and I did wiped own and buffed DV roller to a better print but I need to know is this what this series puts out?

The quality is USUALLY great on these models.... Your quality isn't normal ! I would check your Sim 46 settings and see if anything is out of setting

I have had a couple of these where I needed to reseat the laser cables behind the left side door. We noticed our text was crooked almost like spoofy Chinese characters (see my fake example) that may be what you're seeing blown up into a picture.

Re: MX-M5050 print quality

Just tried both ends of ribbon cable from LSU to MFP pwb. No difference. I checked all the 46's and all are at default. Im still getting the phenomenon. I did order a brand neww DV unit. I'm waiting on that

Re: MX-M5050 print quality

Weird that its happening on 4 different machines. Are they all in the same location? Did you clone all of them from the same file by any chance?

Re: MX-M5050 print quality

Also, does it happen from both self prints and prints sent through a computer or just from a computer?

No Danny. The one thing I have noticed is that the DV rollers are very dark with built up toner on them. I have to wipe them and scrub them to be clean. Thats why Im going to try a new unit which should be here Monday morn. It happens USB and computer printing. None are cloned. These were bought 4 separate orders (used).

Re: MX-M5050 print quality

That is weird but like Danny said, on four machines I would start by checking anything they have in common. Is there any chance the electricity from the walls at the location is faulty? Maybe they are having trouble charging properly, might try putting one on an uninterruptable power supply... Or are they using unfamiliar media maybe? That's super weird to have spread across four machines like that. Do you have any of this model working correctly by chance? Or know someone that does? Maybe a configuration file or reset to factory settings could have an effect. I'm at a loss though, hopefully someone with more experience recognizes it. You said used, any chance they came from the same place with an environmental issue? Good luck man

Re: MX-M5050 print quality

You could also try sending an image to print and force stopping the copier and look at how the image is in the drum. If the image looks good in the drum it could be the fusor or the secondary transfer roller not putting enough pressure in the page. Keep us updated, interesting problem.

1st thing I do M94 when we get machines in is give them a digital enema. So all go back to factory reset. I am the setup and rebuild guy for my company so I know the electricity is fine. This is very odd. Now I do not know if these were from the same place , of course this is possible but EVRY machine gets a full pm and brand new OEM parts so I am hoping the DV unit fixes it.

Re: MX-M5050 print quality

Yeah I'm at a loss man, I kind of assumed you would have checked most of that but figured there was no harm in double checking. Be sure to let us know when it's solved, I'm fairly curious at this point. Fingers crossed for you bud.

Re: MX-M5050 print quality

Can you show us what your shark sample printout is supposed to look like on a "working" machine? Have you tried other photographs/images? It's possible this shark photo has layers which look good on screen but don't print well. I'd be interested to see the original source image if you still have it.

No Danny. The one thing I have noticed is that the DV rollers are very dark with built up toner on them. I have to wipe them and scrub them to be clean.

I'm sure you know this but the DV rollers are supposed to be dirty and solidly covered in DV mixture. If you can see any metal through the black, that is bad. If you clean the DV roller off you're removing material and throwing the calibration of the machine off, unless you're painstakingly saving every bit of powder and putting it back into the unit. They are not supposed to be cleaned except maybe a light wiping during a PM where you're replacing the powder. A "scrubbing" being needed I think would be quite unusual.. maybe for a ancient DV unit with a million+ copies on it. Maybe more common in very humid environments or something but I haven't encountered that.

Check your mixture readout on Sim 25-1.. it should be around 128. If your DV mixture was highly depleted you'd see the characteristic tiger striping, and it wouldn't make that screen door pattern.. so I still think it could be the source image.

Re: MX-M5050 print quality

Hi mate, no idea if you have tried this, but go into system settings and initialise private data to give it a fresh start. We had two machines doing exactly that, really noticeable on Grey scale and wouldn't print out think lines, and lines it did print had weird hatch markings. Tried a dev swap and no difference, was a new machine. Initialized private data, took about 2 hours, then give excellent prints since.

Yes. I have updated the ******* firmware.

I noted that the 1st thing when a machine comes in John is that it gets a digital enema I.E. Init priv data in security settings.

The print from other machines are very nice and fluid. Be aware that I clean the DV roller AFTER DEPLETING IT OF DV, I don't care if it has 20k on it. You can't trust the 22-6 especially on a used machine that comes in the door to be rebuilt. With that said, the reason I clean and scrub the roller is I noticed in the 365 series that on prints, the edges were lighter than the middle. When I went to change the DV I noticed the roller was very dark on the edges. I cleaned then up and put old DV back....VIOLA, great prints again. I should know if the DV unit fixes it shortly. It is supposed to be delivered this morning.
