First time post. I'm getting an E-2 error on an ABDick 9995. The Electrical Service Manual says this is a poor encoder z phase input. The machine jogs fine and doesn't cause an error. When pressing the start button (at any speed) the machine will crawl - slower than the normal jog - for a few inches and then give the error. Pressing the stop button clears the error. Continually starting the machine at the slow jog and clearing the error will eventually get the machine running.

I've tried doing the timing procedure where you put the machine in service mode, put the timing wheel on 0 deg and loosen the encoder and adjust until the buzzer goes off. This doesn't make a difference.

I've taken the motor off and had it serviced (they just replaced the bearings). They said it looked fine.

The incoming voltage to the inverter is 208. The voltages coming off sp + and sp - match the book. There is a 0.08 volt drop when measuring from sp + & - to the inverter wires 2 and 5. Not sure if this is anything or not.

I'm not sure why it eventually starts working. Any ideas of what to check?

Thanks,

Chrome roller in the fount water tray picks up the water
Metering roller is high up on the chrome roller and meters the amount of fount that makes it through the nip
Water form roller goes onto the chrome roller when water forms go onto the plate.

Chrome roller & metering roller are geared together
Water form roller has a separate gear & is geared to run at the same speed as the plate cylinder

This is a water roller system that some other manufacturers use also. I am wondering if anyone has taken the gear off the water form roller and allowed it to be driven by the chrome roller, effectively spinning at the same speed as the chrome & metering roller?
Do you think this will happen, or will the plate cylinder take over and make the water form spin at the same speed as the plate?

I am thinking of giving it a go on Monday, the reason for wanting the water form to spin at the same speed as the chrome roller is we get water beading/ building up between the chrome roller & the water form roller on start up. Once you hit damp on button with in 3 - 5 seconds water starts building up between this point. I'm thinking if the water form & chrome spin at the same speed the fount should pass through the nip more effectively
It doesn't matter what water form to chrome to plate strips are it still happens, nor does it matter what level of alcohol is run.

I know it is a roller hardness or compound issue, but it is the rollers we were recommended by the roller company and there is no chance of a swap now.
Standard starting shore A hardness of the metering roller is meant to be 30
Standard starting shore A hardness of the water form roller is meant be 23

The company has supplied
Westland IPA free compound metering roller 25 shore A hardness
Katsura standard compound water form roller 27 shore A hardness

I believe that both roller compounds need to be the same so that the water passes through the nip the same. As it stands you have one roller that allows the fount to pass through the nip effectively and one not so effectively, plus the fact that the water form roller is spinning at a significantly reduced rate then the chrome on start up leading to the fount building up between the nip.

I have read through the Komori picture framing thread and there is talk about removing the gear from the water form on that press but there are no comments about what will end up driving the water form, be it the plate cylinder or the water roller system through nip pressure.

Any thoughts on the outcome? ]]> Sheetfed/Web Offset Discussion Lukew http://printplanet.com/forums/sheetfed-web-offset-discussion/31228-water-form-gear-removal http://printplanet.com/forums/sheetfed-web-offset-discussion/31215-bossmandan81 Thu, 16 May 2013 21:23:58 GMT Does anyone have any info on setting a Dahlgren water system on a 1976 Western Gear buisiness form web press?

When plates come out of the CTP, you cannot see it because we are using Kodak Thermal Direct Plates, and these are not visible. Once inks hits the plate, the dot is already broken up.
