The instruction video for this maintenance action is available, see Clean the SZ-rollers in the registration output module.

NOTE

In order to keep your hands clean, it is advised to use nitrile gloves when you work with ink, ColorGrip, PML, or SU70. For details see the related material safety data sheets. (Learn about printer maintenance)
Inks, ColorGrip PML and/or SU70 contain 1,2-Benzisothiazol-3(2H)-one. From the point of view of occupational health and safety, it is not recommended that people who are sensitive to chemicals (e.g., people with asthma) work with ink or chemicals.
When you spill any liquid, wipe up the drops with disposable towels and transfer the used towels to a sealable container appropriate for disposal.
