great list, just want to point out a mistake if you dont mind
mxm 850 950 100 uses mx-850df for adf not ar-620 df
also anything that use the ar-620df can (and will work better) use the 850...
it could be defaulted to that size instead of auto size
i know you stated that you replaced the transfer, but they get damaged in shipping all of the time
make sure the color lift rollers in the primary transfer are not broken and that they lift up and down properly. if the one for magenta isnt lifting you will not have the color.
the other...
i think it would be almost impossible to install one of these lsu incorrectly.
if i remember correctly (someone can correct me if im wrong) the early versions of this machine did not have the removable plate below the lsu. i remember because i use to dread doin an lsu swap...
not really flickering, it just does not come on sometimes causing black copies. have seen this before and the mod fixed it. but its already done on this one ( either by tech or factory?)
tech...
I have a mxm620 that is making intermittent black copies. I know this is due to lamp not coming on and there is a tsb mod for it. The mod has already been done to this machine. I'm thinking my...
usually dont assume, but this was a good tech, we have plenty others that the first thing i do is check all the work they already done. oh well just glad it turned out to be somthing simple
have seen this before. intermitent for about 6 months, another tech replaced the cassette pwb but did not seem to work. i went out after and assumed the other tech did it correctly and double...
we had one in the office that did this as soon as it was unboxed. tried everything swapping boards with another like machine. i think my manager finally found it to be the scanner control pwb. i...
run you finger down the mag roller to clean off an area, if it is gray instead of shiny silver. the mag roller will need to be cleaned. after awhile the mag rollers will get coated and have to be...
2 things. have seen one of these do this once after the main drive was replaced. it wasnt installed correctly and when it tried to start up it would say to close the front door. dont remember...
if your asking me, then yes i did. had one of the smaller sharps (cant remember the model, the replacement for the 237 257 ect..) kept doing this also and turned out to be the pcu pwb. hope it...
is it a solid/full page background or just a band a few inch wide of grey backgrond/shading.
havent seen one with full background but have came across one with a background band down the page...
i have been having this same problem with a 453. full pm and copies look excellent for around 5-6k then goes light again. my next step is to repl dv unit. and see what happens
on these the charge rollers are connected to the front door, so when u lift the door it lifts the charge rollers out of the way. i have seen a few where the brackets that hold the charge rollers...
also keep in mind that u cant use "used or boards from another machine" if u do it will brick the machine, cant remember if it wont boot or will boot with a critical error. would make sure the...
yes,,, common,,, replace the acm feed assy and replace the feed clutch (u have to remove the clutch to get the feed assy out anyway.)
the bevel gears inside the feed assy will break and cause a...
yup its the harness. and there was updated firmware to help prevent this from happening (stops the useless and random stapler movement causing wire wear i believe)
power off copier. hold down 2 and 6 and and turn power on (keep holding the 2 and 6) depending on your model it might be the down arrow and the right arrow you need to hold down)
cant find a price for the 782 but for the 792 they seem to be around 190 new or 150 refurb thatll get u in the ball park. and a lexmark psu isnt that uncommon to crap out
very nice info. havent seen this yet but have seen the little white labels on process units and dv units peel up and block the laser. that cost me a couple of hours b4 i figured that out. lol
ccd and op panel go to a scanner junction pwb then to the scanner countrol pwb. the cis appears to go straight to the scanner control pwb. i would recomend trying the scanner control pwb
