To ensure machine reliability and copies of the highest quality, Canon
U.S.A., Inc. recommends that a Quality Assurance Visit be performed
every 250,000 copies. Quality Assurance requires the cleaning, checking,
and replacement of parts as necessary for specific areas every 250,000
copies. The frequency of the Quality Assurance Visits will depend on the
following conditions: monthly copy volume, environment, type of originals
copied and customer’s handling of the copier equipment.

A QA Procedure will require the replacement of various consumable parts
every 250,000 copies.
The Image Processor Printed Circuit Board (PCB) and Multi-Function
Controller (MFC) PCB are each equipped with Double Inline Memory
Module (DIMM), which contains Flash ROM and Firmware programmed
into each DIMM.
Note:
The “Original Orientation Detection PCB” is located near the IP PCB of the
imageRUNNER 550/600. It is also equipped with DIMM, which store
fonts, and has 72 pins. DIMMs are labeled by memory capacity and
purpose of the DIMM (mentioned on it) to distinguish the difference
between these DIMMs and the DIMM for the Original Orientation
Detection PCB.
A Personal Computer is required when installing upgraded firmware. Use
Bicentronics I/F cable

as an interface between the personal computer and
the imageRUNNER 550/600 to enable high-speed transmission of the
data. The required time to complete the upgrade is approximately ten
minutes.

The following Bicentronics I/F cable is required: One end of the cable should have a TYPE A connector prescribed
by IEEE1284 (25 pin, for PC connection). The other end should have a TYPE B connector (38 pin, for copier
connection). Cables conforming to the IEEE1284 are marked “IEEE Std. 1284 compliant”.
