IBM 1140 chirping noise coming from left side of print when documents print
The company I work for uses an IBM infoprint 1140. I'm hearing a chirp noise while documents print from the left side of the printer.
I removed the left cover and I can hear the noise from under the plastic safety cover. The first gear you can see is a shaft that is turned by
a series of gears behind the shaft. Furthermore, I don't see any worn parts. Any ideas on what can cause a chirping noise ? ie. bearing, worn part, etc. ?
