AR-M350 Locks up...HELP Please

[Buddy]

I've never seen this. After turning the copier on, I'm able to make one change on the touch screen. I tried to disconnect the finisher and duplex unit. I've done the touch screen adjustment, SP65. If I'm in the SP mode I can play with the keys as much as I want and they keep working (both the number keys and the touch screen). But as soon as I try to make a copy, I can only get one change on the touch screen and then it just freezes. Any ideas will be greatly appreciated.Thanks

has some one been playing with the --Key operation setting-- hold down a key for more than 2 seconds

system settings

Enter Key Operator Code

OPERATION SETTINGS

KEY OPERATION SETTING



These programs are used to set the length of time a
key in the touch panel must be touched before the key
input is registered, and to prevent repeated key input
when a key is touched continuously.
• Time until key input is registered
The time can be set from 0 seconds to 2 seconds in
increments of 0.5 seconds. Normally the time is set
to 0 seconds so that key input is immediately
registered when a key is touched. By lengthening the
time setting, key input can be prevented when a key
is touched accidentally. Keep in mind, however, that
when a longer setting is selected more care is
required when touching keys to ensure that key input
is registered.
• Prohibit key repeat
The touch panel contains keys such as the zoom
keys (for setting the ratio) that can be touched
continuously to make a value change until it reaches
a desired value.
This feature whereby a value changes continuously
while a key is touched is called key repeat.
Key repeat is normally enabled. If you wish to prohibit
key repeat, select the "DISABLE AUTO KEY
REPEAT" checkbox.

Thanks mxm. Unfortunately, it didn't help. The machine works fine for anywhere between 1/2hr to an hour. It then goes back to freezing. I'm going to try another op panel tomorrow, unless you have another idea. Thanks again.

I would suspect the HDD, any E7 codes in the history?

Thanks guys. I should have posted the fix. It was the op panel. Thanks again.
