touch screen calibration

[turkeyfoot]

Can the op pnl be intialized on a 4500 for a desensitized area ? The lcd doesnt respond in certain areas.

[KopyKat]

You can try the calibration but chances are that you have a defective touch screen, a bad or loose connection, pinched ribbon cable or even a bad solder joint.

Is this in an environment with those lovely users that like to slam their fingers or worse yet pens on the op panel? Examine the board closely and if you find any cracks...bill 'em!

Ive looked through a ton of sp codes, nothing yet, can you tell me how to calibrate the screen?

[KopyKat]

Here ya go. Same for most all the Ricoh Family Group copiers.

Thx!

Calibration is not the solution.Unfortunately the touch screen on this model is not very reliable.Check RB296020 new P/N H3109900

I agree with reliability statement, if you need to calibrate then you will most probably need to replace the top screen

[turkeyfoot]

Thx for the timely info. I found the Ricoh site down for tech bulletins. It must be Thursday.

Don not order a new display yet. First please check with the local Ricoh branch. It's a program in place to replace lots of displays for various models starting with Adonis. We just received this information from Japan. They found out some panels that are affected by moisture.
Provide them the serial number of your machine and they will be able to tel you if you are eligible to obtain for free a new panel.
I don't know details at the moment but the program should start (at least in W Canada) this summer when it will be slow....just in Calgary we will replace ~1000 panels.
Good luck

Thank You KopyKat. The pdf solved our problem.

Hi- thank you for the PDF, but do I need to be in a specific menu to type the code? I've tried to enter the code when in Admin mode, but I'm unable to enter Admin mode due to my touchscreen being off - vicious circle!

[Vulkor]

Nope, from the normal copy screen it's just as you saw in the PDF.

Dear Friends. i have tried to solve problem with PDF but i have a problem. I wanted to calibrate the screen but i cant touch the point(technical). I am touching on it but there is no effect.When i want to test Touch screen, i am marking a point but it appears wrong. My printer is Ricoh MG c2500. Could you help me please ? Do i have to chance the screen.

Yes, you do have to change the touch screen, it's failed completely. Part number is B223 9900.
