The Printed Paper Has Vertical Streaks

<Cause 1> Depending on the paper type or the operating environment, vertical streaks may appear on the printed paper.

Solution 1	Replace the paper with new paper in an unopened package. "Precautions for Paper"
Solution 2	Perform the following procedure in the printer driver. 1. Display the [Finishing] tab. 2. Click [Advanced Settings]. 3. Set [Special Print Adjustment C] to [On]. You can specify the same setting from the printer's control panel. "[Setup] Menu ([User Maintenance] Options)" Resetting the setting to [Off] due to change in paper type or operating environment may also avoid vertical streaks appearing on the printed paper. In this case, reset the setting to [Off]. If you specify this setting, printing speed drops.
Solution 3	Perform the following procedure in the printer driver. 1. Display the [Finishing] tab. 2. Click [Advanced Settings]. 3. Set [Special Print Adjustment A] to [Mode 1]. If the problem is not solved, specify [Mode 2]. If the problem is not solved, specify [Mode 3]. If the problem is not solved, specify [Mode 4]. You can specify the same setting from the printer's control panel. "[Setup] Menu ([User Maintenance] Options)" Resetting the setting to [Off] due to change in paper type or operating environment may also avoid vertical streaks appearing on the printed paper. In this case, reset the setting to [Off]. Vertical streaks are alleviated by specifying a setting between [Mode 1] and [Mode 4]. However, this decreases print density compared to when [Off] is specified. This may also make outlines appear to be blurred or slightly jagged. If outlines are jagged, select [Off].

<Cause 2> The toner cartridge was replaced, or the printer was not printed for a long period of time.

Solution

Perform the following procedure in the printer driver. 1. Display the [Finishing] tab. 2. Click [Advanced Settings]. 3. Set [Special Print Adjustment B] to [Mode 1]. If the problem is not solved, specify [Mode 2]. If the problem is not solved, specify [Mode 3]. Selecting [Off] may also avoid vertical streaks appearing on the printed paper. In this case, reset the setting to [Off]. If you specify this setting, printing speed may drop.

<Cause 3> Damp and thin paper (60 to 74 g/m²) is used.

Solution

In the printer driver, set [Paper Type] to [Plain L] and [Special Print Mode C] to [On]. "Configuring the Printer Driver and Printing" [Special Print Mode C] can also be set using the printer's control panel. "[Setup] Menu ([User Maintenance] Options)"
