7.10 Part Quality Issues - Streaky or Striped Parts, Delamination

Explanation: Streaky or striped parts are caused either by powder buildup on the print head, a failed print

head, or an electrical issue within the printer. Delamination (layers splitting apart) may be due to a print

head that is caked with powder, or a pause in network communications.

Solution - Both:

• Clean the service station. See Section 3.5, ’Clean The Service Station’.

• Clean the parking caps. See Section 3.3, ’Clean The Parking Caps’.

• Ensure the printer has cleaning solution.

• Realign the print heads to ensure proper alignment.

• Clean the Fast Axis Rails of any debris and reboot the printer. See Section 3.4, ’Clean The Fast

Axis Rails and Carriage’.

If the problem persists,

• Clean the pogo pins and the print head contacts.

• Realign the heads. If the pattern shows striping or streaking, one or more print heads may have

failed. Change the print head and realign the heads. See Section 7.4, ’Alignment Errors’.

Additional Solution - Delamination

Check your PC settings. The printer may be pausing as it waits for additional data from the PC. While

pausing, the printed part begins to dry and as a result the next layer does not stick to the last layer printed.

Your PC should be dedicated to ZPrint. Your PC Power Management software should be completely shut

off.
