The tension of all toothed belts, with the except of the carriage drive belt, is not critical and
can vary widely before the operation of the printer is affected.
When you carry out preventive maintenance, also check the toothed belts for excessive
slackening.
The only preventive maintenance required for the MSF is the regular removal of dust and
paper particles from the edges of the plastic protective panel in the R/W head slot.
