Printer wont complete boot sequence
ANSWER : That’s a really old machine, I had helped someone replace a belt a year or 2 ago in a 450 also. Opened it up & when I went to release the belt motor (I think its called a scan axis or carriage motor) the plastic arm that wraps around a metal bar was cracked. Put the belt in anyway but it must have been bad enough as it would throw an error, I think he gave up and replaced the machine but don’t remember. Some parts like this are hard to find & if found are likely used and could suffer the same failure again since plastic gets brittle as it gets old.
