Epson SureColor P600 - Persistent 0x53 startup error

[Rick76]

Hi everyone,

I'm hoping someone familiar with the Epson SureColor P600 can help point me in the right direction. My beloved P600 has suddenly developed a persistent startup error after 7 years of flawless performance.

Symptoms:

• Error code is 0x53 about 99% of the time (occasionally 0x01).
• Printer powers up normally.
• Print carriage initializes and travels across the printer.
• During initialization the carriage moves in several small, slightly jerky increments before moving normally at full speed.
• The carriage is not physically stuck.
• After the carriage initialization, I hear the paper feed motor initialize.
• Immediately afterwards the printer stops with error 0x53.

Things I've already checked:

• Carriage slides smoothly by hand with the printer powered off.
• No paper scraps or foreign objects.
• Carriage guide rod is clean.
• Timing belt looks normal.
• Encoder strip has been cleaned.
• Maintenance station appears clean and doesn't appear jammed.
• Cycling power and leaving the printer unplugged has no effect.

The printer has never been dropped or transported roughly.

At this point I'm trying to determine whether this is more likely to be:

• maintenance station drive
• maintenance station position sensor
• carriage encoder sensor
• home sensor
• main board
• something else

Has anyone seen a P600 consistently produce 0x53 with these symptoms?

I'd really appreciate any advice before I start replacing expensive assemblies.

Thank you!
