Carriage driver board power supply noise causes errors, device resets

Trendsetter spontaneously resets during plotting or reports firmware errors 38171 or -46


Product		Trendsetter 400/800 (TSM) Trendsetter ContinuousLoad Trendsetter Autoloader (TSM) Trendsetter/Proofsetter Spectrum (TSM) Trendsetter NEWS (TSM)

Machines affected		TM520 and below NM253 and below

Component		Carriage driver board, carriage driver board power cable

Error		`38171 MPC: Raster image data received from workstation was possibly corrupted. Check plate for artifacts.` `-46` (low level firmware error)

Symptoms		Output device spontaneously resets during plotting CRC check errors such as #38171 or low-level firmware errors such as #-46. Digital I/O errors

Cause		FCO CA00752 introduced a new carriage driver board (part number 503C01525B) for various Creo output devices. This board has a switching power supply that generates a high level of electrical noise, which is fed into the MCE board via carriage driver board power cable 220-00061A.

Solution		Perform FCO CA05160: Remove power cable 220-0061A and install power cable 220-00163B, connecting the carriage driver board directly to the carriage power supply (PS2).
