Brother MFC L8900 CDW intermittent prints are reduced to half size with several diffe

[tonerjockey]

Hi guys, i have a customer that said maybe once a day, when they are printing, the print comes out about half size. they turn off the machine and then its ok.

it doesn't matter what program they are using, and several computers are all doing this. sometimes email, checks, etc.
i would think if they had inadvertently selected a reduced or fill to page, print actual size, etc, then all the computers wouldn't do this, nor would rebooting the copier resolve that issue.


i am sort of perplexed at this point. and being intermittent, well, that's harder.

does anyone happen to have any ideas, or experience with this type issue??


thank you very much, Jim

At first I will blame program/PC for this problem, but obviously that wouldn't apply in your case. I could think of 2 remedy:
1. Update Firmware - think latest is L 1.10
2. Initialize EEPROM parameters (function code: 01, 91)

Hi guys,

I have updated the firmware, and the issue is still happening intermittently. now here's an interesting observation. the print is reduced one way, but not the other.

another words, prints are to narrow from left to right, but the height from top to bottom is ok.


any additional ideas? thank you very much, Jim

Sounds like a scanner timing or drum timing issue.
Is the ITB slipping ?

PCU's and Dev units turning freely?

I've seen a failing LSU cause distorted images, and images shifted 2" off one side of the page, on a Sharp. Nothing on a Brother.

Is your information anecdotal, or can you see specific instances of it happening, and what functions are in use at that time? I've come to understand that such second-hand information like this can be slightly false or completely false, and the accounts colored by the amount of drama desired by the storyteller.

Let's see some of those samples. =^..^=

so for example, when they print a check and it happens, the info fits top to bottom, but all the info that goes in certain areas on the blank check, is all shifted to the right about the middle of the page over to the right. nothing is missing, just the size is 50% narrower than normal. so its scruntched into half the page horizontally.

i will try to get a smaple.

lets see if this uploads. i haven't done it much on this site.

the image isn't the clearest, but its a blank check for printers, with the printed info all on the right half of the page. but the height is ok.


well, when i follow the sites instructions to drag and drop to that pane, i get another window that opens, but its not attached to the copytechnet page?? maybe it takes a while to be reviewed?

Can you print 77 list from service mode? There will be the last 10 errors, may find something like a service code related to abnormalities. Also text shrift is halfsized and then shifted to the right or just space between symbols are narrowed and shifted. Please try again to upload sample if possible.

the upload system is whacko.

i see the generic PDF icon in the "manage attachments" pane, but i dont see it here.

Copy paper appears to be offset.

Using paper tray:
Is the paper sitting centre in the paper tray?

If using manual paper feed:
Do the manual feed paper guides sit centre when closed completely. Haven't jumped a slide tooth.

The offset lead edge can be adjusted in service mode.

they have had the machine over a year. the paper Drawer is always full and used.

they print for a week, and all is fine. then they get a print that's reduced one direction, and then it does that until they turn Brother MFC off and back on. then everything is fine for a week or so. happens once a week average, but this last time, was fine for a week, then did it twice in a day.

i happened to see this old post, so will add additional info.

brother had me try a few things, and then said they would like for like it. but the customer decided to live with the problem, as brother said the replacement machine would be a "refurbished". but still, that was nice of them.

so, the machine still does it from time to time.
