Web Guide Adjustment
The AVERY DENNISON 656 / 636 printer has been designed with only three web
guides in the printer that need to be changed as the width of the rolls change from
format to format. None of these adjustments requires any tools.
The first guide is on the unwind itself. A knob located on the front of the unwind
adjusts the width of the guides on the unwind while maintaining center justification.
To increase the width turn the knob counter clockwise to decrease the width, turn the
knob clockwise. Adjust the unwind width wider than the roll of stock to be loaded.
Set the stock roll on the unwind between the guides with the stock unwinding from
the top clockwise. Adjust the unwind width down to the stock size without clamping
the core.
The second sets of guides are located on the decurler just to the left of the stock
registration funnel. Once a stock is loaded and tracking straight through the printer
adjust this set of web guides down to the edges of the stock without deforming the
stock. Loosen the plastic thumbscrew and slide the collar into the new position then
retighten the thumbscrew. Fine adjustments of the stocks web position can be made
by simply moving the collar as a set in or out. If the guides are too tight, the stock
will have rolled up edges.
The only other web guide adjustment is the stacker up-right rails (refer to the Stacker
Adjustments section in this manual). To fine turn the location of the up-rights, loosen
the knob behind each upright rail and slide the rail in or out as needed. The up-right
rails should be located approx. 1/16" (1.5mm) to the back or front of the label or tag
as it enters the stacker.
Print Head Operation
The print head module is to be opened and closed for threading the stock and ink.
The head must also be opened to clean the head and for print head replacement.
Later in the manual, under Print Head Cleaning, and Print Head Replacement,
cleaning and replacement will be covered.
The print head has an interlock switch that prevents the printer from running with the
head in the open position. If the head is open the display will read - HEAD OPEN.
WARNING: DO NOT TOUCH THE PRINT HEAD WITHOUT WEARING THE
ANTI-STATIC GLOVES AND THE STATIC WRIST STRAP.
To open the print head for threading supplies, press the lower portion of the latch
(see figure 7). The head mount plate will hinge from the back to swing open.
