Die Set Maintenance; Preventative Maintenance Schedule - Ricoh B234 Service Manual

3.4

DIE SET MAINTENANCE

Die sets have a minimum life expectancy of 500,000 cycles depending on application, environmental
factors and maintenance. Periodic lubrication of the punch pins can extend the life significantly. GBC
recommends use of a high quality machine oil (3 in One Oil or better – do not use spray oils) every
50,000-punch cycles. The customer/operator should perform this maintenance between Technician
inspects (below).

PREVENTATIVE MAINTENANCE SCHEDULE

The following preventative maintenance should be performed during the regular printer inspection
intervals (350K & 600K etcetera).
• Check web site for any bulletins; bring StreamPunch up-to-date as required.
• Disconnect the main cord set and retain it in your control for your safety.
• Remove the rear cover.
• Perform a visual inspection; clean, adjust and replace components as required.
• Vacuum Paper Chad out of Back Gage Mechanism and Die Guide as well as base.
• Optical Sensors; Remove dust and particles from the lens using a soft cloth.
• Inspect Timing Belts for wearing or fraying.
• Inspect any Latching Mechanisms, clear any jams paper debris.
• Inspect and clean Rollers.
• Inspect Left / Right Punch alignment by running paper with each die set, check for even hole
alignment by folding the paper in half. If adjustment is required, ensure that the Die Latch is
properly adjusted.
• Inspect the Door closing latch for proper alignment, if bent, instructs the operator to avoid closing
the door with paper path latches out of place.
• Lubrication of the Die Set Pins (see note above)
• Cams (when punch is pulled), lubricate with high quality grease
• Inspect the Idler Rollers, clean if necessary.
• Inspect the Drive Rollers, clean if necessary.
• Inspect the Paper Path Panels, clean if necessary.
• Inspect each Die Set for wear. Run at least 100 sheets of paper. Look for signs of excess paper
jamming. Inspect the hole quality. Hanging chad or ragged holes can lead to paper jams. If the hole
is cut sharp enough that there is no hanging chad and the paper passes through the system
without catching and jamming, the die set still has life.
As with any electro-mechanical device, isolated component failures may occur. GBC does not
recommend preventative replacement of components until the printer has reached the two million-
impression milestone
