10/3/2012 light strip on prints

PIP wasn't printing up to the proposed impressions, around 25000 to 32000 when it should be around 65000.

There is an about 9mm lighter shaded strip measures about 65mm from the edge of paper.

Usually replace the PIP will resolve the issue, but I thought there must be something wrong that causes the PIP to go bad before it's intended lifespan.

Called HP support, Case # 4683563483.

Things checked:

- Check and run the Cleaning station calibration, and see if the PIP is getting enough imaging oil.

- Check the tray underneath the cleaning station to see if loose.

10/29/2012 - White banding

Again, we got this white 1/2" white banding near the leading edge of the prints.  It happens to every other sheet.  Usually changing the PIP will resolve the issue, however, our PIP didn't get the HP suggested impression count and started showing the band.  This time around 4000 impressions only.

Solution:
1. open the back of the press, near the turning wheel, you see a black screw cap that covers a wire.  Unscrew the black screw cover, take out the spring wire thing, clean the rectangular shaped copper block attached to the spring with IPA.  Use a cotton swab with IPA and clean the hole while turning the itm wheel. Put everything when finished.

2. Run auto bias.

3. Be sure the tray that is below the cleaning station is sturdy, not moving.  If not sturdy, screw it tight.
