Blockage Caused By Knocking And Strong Vibration - EC-PACK EC-JET 1000Pro Manual

Knocking and Strong Vibration
Strong vibration and knocking to the print head is the most serious vibration problem likely to occur, since
this will affect operation of the printer itself. Severe vibration or knocking will lead to the printer shutting
itself down and displaying one or both of the following fault messages:
" 2.01 Deflector Voltage "
" 2.03 Velocity of Drop "
It will also be found necessary to clean the print head more often than would be expected.
To understand what is happening, consider that the stream of drops is relatively stable once in flight.
Therefore, if the print head suffers vibration or sudden movement, the drops will be obstructed either by
the VOD sensor or the edge of the gutter. This will cause ink to be splashed on the VOD sensor and
deflector plates, and to build up deposits on the gutter.

FC39 No Print - Print Delay Problem
Normally, when the system detects a product passing the photocell, it will activate a "print go" signal
which causes the current message to be printed immediately. The Print Delay option of the SETUP menu
is used to delay printing to allow the product to travel further before printing, thus controlling exactly
where the message is to be printed. For instance, if the product is a long one and the message is to be
printed in the middle, it will be necessary to set the delay to a value appropriate to the speed of the
conveyor and the length of the message, which will cause printing to occur at the desired place.
What actually happens is that when the system detects a product passing the photocell, it will delay
printing by counting the number of raster it would have printed, until that count becomes equal to the
value of the Print Delay option.
