arm355 no paper condition

[Silvertoast]

i have a arm355u that is sayin no paper in tray 1 (there is paper in tray)

the paper is not lifting up. the machine knows when the tray is pushed in just doesnt lift. have tried a new lift moto and pcu so far.

the sensor that detects the tray installed and the sensor that detects the paper when the tray lifts up are working properly

thinking mayb the dc board or the moto i tried is bad also?

opinions/thoughts?

Re: arm355 no paper condition

Do you hear the lift motor running when the tray is closed? It's been quite a while since I've dug into one of these.

I do remember that to get full access to the tray #1 feed roller area you have to remove the engine and flip it on it's side. Fun, fun, fun.

Re: arm355 no paper condition

the moto doesnt run. took the lift moto/unit out and held it in my hand while i actuated the tray sensor, . thinkin mayb no dc volt to it. when i go back im takin the meter in to check ( the machine is upstairs in a plane hanger across an air field and large parkin lot, so i travel as light as possible) so i didnt take my meter with me today

Possible tray one paper lever detector broken

Re: arm355 no paper condition

I think there are 2 different senors that deal with tray lift. You may want check both thru simulation. We had one that we replaced both switches and the wireing harness and pcu pwb and ended up being one of the switches from sharp was defective. Good Luck

Re: arm355 no paper condition

Did you get a U6-xx error code at some time on this? You may need to reset using sim 15 or 17, can't remember which, try both and see if it resets the drawer. Have had to do this on occassion to get the drawer to start working.

Good luck.

Re: arm355 no paper condition

no u6 codes, tried sim 14-17 anyway. as stated above both sensors are working properly under sim 30

takin another motor and my meter tomorrow to see if i just had a bad one and to see if im gettin power to the moto

Are you sure the tray is not lifting up? It can be hard to tell since you can't see the tray while it's pushed into the machine. I have seen this condition many times when the machine is looking for a different size paper then what's installed. ex. The machine wants to print on A4 paper but letter size is installed.

Maybe your arms are a lot skinnier than mine, but my arms don't fit and there is nothing modular. =^..^=

Re: arm355 no paper condition

yeah im sure. when i hold the lift unit in my hand and press the sensor , the moto is not turning on. also when u open the tray u do not here the tray droppin down , (which is loud on these machines)

Re: arm355 no paper condition

update. have tried new lift moto unit and one from a known good machine

swapped wiring harness from moto to pcu

tried new pcu

swapped ac/dc board from working machine

swapped high voltage simply because im shootin in the dark at this point

called sharp service support and checked all voltages and all are good except the volt to the lift moto when activated.

sharp service is stumped on this one and so am i.

only idea tech support had was shorted wire, but i swapped the harness with a good one and ohmed out the rest of anything that could be related.????????

Have you try to swap the tray 1 also?

[Silvertoast]

Re: arm355 no paper condition

^^^ the tray only has the gear that lifts the tray up so that isnt the problem.

gonna swap the engine(box) with another one tomorrow. service manager says we have wasted too much time on it already

would still like to know if anyone has seen this b4

Re: arm355 no paper condition

The reason I had to flip over the engine was to change out the separation tire holder. The post on the rear side busted off. =^..^=
