IR2525 vending extra page

[oldschool]

A tech called me with an odd problem. He has a Jamex 6557 vend station on an IR2525. To set this up you'd normally set Copier-option-acc to 1 (coin) an Option Acc CC-SPSW to 1. The copier is disabled and the insert coin message is on the display until money is used. If the patron selects more copies than credit the IR2525 feeds 1 extra sheet each time. The attached vend device is only a simple 4 wire key-counter interface so there is only a relay on 2 wires to bring the copier ready and an opto-isolator on the other 2 to detect a voltage pulse from the copier. Once the vend station opens the enable relay disabling the copier, it's up to the copier as to what happens next. I had the tech check with a meter and he said the disable signal from the vend station happens when it should (Patron runs out of money) but then an extra sheet is fed. The tech tells me the IR2525 firmware is up to date and he wasn't aware of any copier settings that would change this behavior.
Is anyone else seeing this?
Have I missed a copier setting?

Re: IR2525 vending extra page

After properly installing the third party device with the copy control interface cable follow the following steps:

1. Perform "ALL CLEAR" in Service Mode

2. Under Accessories in Service Mode, change the following:
- COIN = 0 to 1 [if set to 1, press #1 and hit ok anyway]
- CC-SPSW = 1 [if set to 1, press #1 and hit ok anyway]

3. Turn OFF & ON machine.

That is what was done. The only exception is the Tech told me after the all clear he had to turn on CC-SPSW first, power cycled the copier and then set the coin option and power cycle copier. He said if he didn't do the steps in this order the copier did not work correctly. The copier would not show the insert coin message and the patron could press the start key before putting in coins. The MFP would scan but not print the page. He has the copier set up correctly and he gets the proper message on the display. He still can get an extra page. The IR2525 is the first Canon I've seen do this. The copier is set up correctly and the vend device is working correctly. It looks like one of those issues Canon needs to address.

Thanks for the input!
