Roland BN-20 Assy, Cap Top 6701689040
Roland BN-20 Cap Top Assembly – P/N 6701689040
The cap top is one of the most important maintenance components on your Roland BN-20. It seals against the printhead when the printer is idle, preventing ink from drying in the nozzles and maintaining the vacuum needed for effective head cleaning cycles. A worn or cracked cap top leads to dried nozzles, failed cleanings, and eventually permanent printhead damage.

When to Replace
Replace the cap top when you notice: failed or weak head cleaning cycles, ink drying in nozzles overnight, ink leaking around the capping station, or visible cracking/deformation of the cap seal. Regular replacement every 6–12 months (depending on print volume) is recommended as part of a preventive maintenance routine.
Pro tip: Always replace the wiper felt and wiper blade at the same time as the cap top for a complete maintenance service.
