Clean Roller, Blade, and Snowplows

CAUTION: Hand-wash only for all printer components and accessories.

CAUTION: Ensure that all powder and printed parts are below the top edges of the Feed and Build Bins prior to this procedure. Failure to do so will lead to a collision with the Roller during the procedure.

CAUTION: To avoid warping, do not use hot water when cleaning any of these components. Use warm water instead.

CAUTION: Before performing any preventative-maintenance procedures, unless a procedure specifically calls for the printer to be turned on, power the Printer down according to the section Shut Down Printer.

 

Frequency: Daily, or as needed after long print jobs (> 3 hrs.)

Clean Roller

  1. Ensure the printer Hood is closed. If performing this task with other daily maintenance, go to settings-cog.jpg > Maintenance > Daily Cleaning. If doing this task by itself, tap Clean Roller on the Maintenance screen.

  1. The gantry will mechanically stop just short of the end of the rails. To gain better access to the end of the roller, it is recommended that you manually move the gantry to the end of travel, as shown at the right.

CAUTION: Take care not to drag or scrape the Roller on the front bearing, or other parts of the printer. Always pull the roller out with both hands to pull it out as smoothly as possible, so as to avoid damage to the roller and other machine parts.

WARNING: Use caution when cleaning. Blade is sharp and is a cutting hazard.

 

While the Roller is out of the machine, clean the blade with warm water and a clean, dry cloth.

Reinstall Roller

Line up the hollow feature on the roller bar with the key feature on the roller motor, and carefully move the roller bar until it stops over the key.

The roller bar is not fully seated until it is flush with the motor wall.

Reinstall Snowplows

  1. Reinstall the snowplows in their appropriate locations, with the handles facing away from the roller assembly. The small magnet on the plow will pull it toward the roller.

  1. If running Clean Roller by itself: on the touch screen, confirm that you have reinstalled the Roller. If reinstalling the roller as part of Daily Cleaning, proceed to the next daily maintenance item. If the printer detects that the Roller is not fully seated, you will see an error message.
