Random double-feed
With good quality paper and correct installation of the sheet feeder, a random double feed rate on
maximum 1/1000 must be accepted. If the fault frequency is higher we recommend that you
check the paper and installation against the following priorities. This following is a summary
from our experiences of a large number of Everest printers on the market.
a. To ensure a good paper quality look at the following details:
* Properly cut paper - never use separated fan folded paper
* There should be no binding holes or perforations on the paper
* The paper should have a rough surface (similar to copy paper)
* Paper should be flat and without damage
* Check that the card/sheet selectors are in the correct position. Test by changing between
sheet and card, using the same paper. We recommend use of the sheet position if it picks
up the paper properly.
b) To ensure good installation of the sheet-feeder, look at the following details:
* The margin guides should slightly touch the paper and be properly locked
* Are the card/sheet selectors in the correct position?
* The paper supports must be correctly installed.
c) To ensure good paper out control, look at the following:
* The document guides (green plastic) should be in the correct position, especially if light paper
is used. The correct position is about 5 mm from the side edge of the paper.
* If heavy Braille paper is used we recommend not using the document guides. Simply slide
them out from the paper area.
d) Avoid low humidity locations.
If the Everest is used in a room with low humidity, static electricity can cause the paper to
stick together. In this case we recommend an increase in the humidity and opening a new sealed
package of paper. Low humidity can also occur in a low temperature area or in an air
conditioned room.
E) Maintenance of the sheet feeder.
* We recommend a clean and rub up of the surface of the pick up rollers after 2,000-10,000
pages.
Clean the pick-up rollers with soft soap solution, or even more efficient is to carefully ruff up the
surface with a piece of fine sand paper. Hold the clutch against the pick up rollers when pressing
Form Feed key.
4.3.2
No paper feed.
The “no paper feed” situation can occur when the sheet position is used for heavy or very stiff
paper.
We recommend switching to CARD position and testing again. No feed can also be a result of a
combination of reasons such as; dusty pick-up rollers, damaged or holed paper and improper
paper installation of the sheet-feeder.
