Location of the paper path module

Before you begin

You need the following items:

Cleaning cloths (Alphawipe pads Texwipe TX1004)
Bottle of process maintenance liquid (PML)
The instruction video for this maintenance action is available, see Clean the SZ-rollers in the paper path 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.

	Action
1	Open the front door of the paper path module.
2	Squeeze the green handles to open the paper guide.
3	Pull one leaf spring towards the front side and at the same time push the other leaf spring (at the opposite side) towards the back side to open the SZ-unit. NOTE You cannot easily get access to the leaf spring on the inside of the module
4	Moisten a cleaning cloth with PML. Use the cloth to moisten the upper and lower rollers. Turn the rollers to moisten the complete surface.
5	Wait for about 10 seconds to let the rollers absorb the PML. Clean the upper and lower pair of rollers. Rub the moist cloth across the rollers from the side until all pollution is gone. Turn the rollers to clean the complete surface. NOTE The color of the roller can change but this cannot damage the printer.
6	Push firmly against the middle of the unit to close the SZ-unit. Make sure the unit is also locked in place at the rear side.
7	Close the paper guide with the green handle.
