Inspect the die sets
Introduction
Die sets have a life expectancy of approximately 500,000 punched sheets. The life expectancy
depends partially on the used media types. The life expectancy of the die sets can increase, for
example:
• When you observe the lubrication schedule (see
Lubricate the die sets - Lubricate the punch
pins on page 177
).
• When you punch the same media type most of the time.
• When you punch less cover stocks.
You must periodically inspect the die sets for wear. The result of the inspection can be one of the
following.
• The die set is not worn. You can continue to use the die set.
• The die set shows signs of wear. You must replace the die set.
NOTE
When a die set reaches the end of life, the die set can cause paper jams.
When to do
Inspect the die sets after 500,000 punched sheets and consequently each time you lubricate the
die sets.
NOTE
See Replace a die set on page 175 for information about how to remove and insert a die set into
the die set slot.
Illustration
[54] Inspect the die sets
Procedure
1.
Put the die set on a table.
2.
Put your hands on both ends of the die set and push the top plate straight down.
Check if the die set functions smoothly. If not, the die set is worn.
3.
When the die set seems OK, insert the die set into the die set slot.
4.
Run a number of sheets through the machine and inspect the holes.
• The holes must be clean and even. Torn or frayed edges indicate wear.
• The holes must be punched completely. Chips that are still attached to the holes indicate wear.
• The holes must be straight, evenly spaced from the paper edge and correctly aligned. Skewed
holes indicate wear.
