4. PF initialization 4-1.The PF Motor rotates clockwise for approximately one second.
4-2.The PE sensor checks if paper exists, and the PF Motor rotates clockwise for approximately 0.5 seconds.
5. Low temperature operation sequence 5-1.The carriage moves back and f orth between CR lock and the left Frame two times.
6. Checking waste ink overflow 6-1.Reads out the waste ink counter value of the Maintenance Box to check waste ink overflow.
7. Detecting ink cartridge and initializing ink system 7-1.The carriage moves slowly to the ink detection position.
7-2.The Decompress Motor is driven and Diaphragm Pump sucks the ink in the ink cartridges.
7-3.While monitoring the ink end sensor, the Decompress Motor is driven again and the Diaphragm Pump sucks the ink.
7-4.Detects the ink remaining.
7-5.The carriage returns to its home position.
Note *1: On the premise on this table, PG does not change and the Rear ASF does not operate during the sequence. *2: Executes when the detected temperature is under 5
(41)by the thermistor on the Printhead.
*3: The Printhead is capped with the Cap of the Ink System but the Carriage is not locked by the CR lock in order to shorten the time before printing starts. The Carriage is locked when the printer enters the power saving mode without any operation after it is turned on.

Note *: For error codes, see Table 1-2 "Fatal Error List" (p.15). Power failure log*2 (Fax Log)
The information stored in this log is the same as the communication log.However, since the airtime is “Unknown” in this case, the result of it is recorded as “power failure”.
Nonvolatile memory
Note *1: The latest communication log for all destinations are printed in a list from when the sequential broadcast is executed. Cancellation is treated as a normal termination, therefore, if it is cancelled, the latest log is printed when the auto print setting is “always print”, and not printed when the setting is “only when an error occurs”. If “only when an error occurs” is selected, the log is printed even when an error occurs for just one destination. *2: The power failure log when the sequential broadcast is being executed is not printed for the destinations to which the transmission log is already complete then. If the power failure occurs before the scheduled sending time when a broadcast is scheduled, the scheduled sending time is recorded.
The communication log is not stored under the following conditions:
Troubleshooting
When the sending operation is canceled which storing B&W image or waiting for redialing.
In the case of a power failure during the operation of sending/polling reception including waiting status for redial, or during receive operation.
When the receiving operation is canceled before the fax signal is detected.
If the fax signal is not detected during receiving operation.
If cancelled during the sequential broadcast. (The log for the destinations of “not dialed yet” or “waiting for redial” is not saved except for those of which the communication is complete.)

Revision B
3.1 Required Adjustments The table from the following page lists the required adjustments depending upon the parts being repaired or replaced. Find the part(s) you removed or replaced, and check which adjustment(s) must be carried out.
After all required adjustments are complete, use the “Final check pattern print” function to print all adjustment patterns for final check. If you find a problem with the printout patterns, carry out the adjustment again. When replacing the Main Board and the Printer Mechanism (Frame Base Assy) at the same time, the adjustment should be made after performing the initial setting.
In this manual, the product name is abbreviated to such as “WF-5620 series”, however, the last digit of the actual name may differ. Identify your product with the first three digits and refer to the appropriate sections in this manual.
The table items and marks used in the “Required Adjustment List” provided on the following pages have the following meanings. • “O” indicates that the adjustment must be carried out. • “---” indicates that the adjustment is not required. • The “Mechanism Adjustment” should be performed just after reinstalling or reassembling the part or unit. (See "Table 3-1 Required Adjustment List (Mechanism adjustment) (p186)".) • The “Adjustments using the Adjustment Program” need to be performed after reassembling the printer completely. (See "Table 3-2 Required Adjustment List (Adjustment using the Adjustment Program) (p188)".)
Adjustment
If you have removed or replaced multiple parts, make sure to check the required adjustments for the all parts. And when multiple adjustments must be carried out, be sure to carry them out in the order given in the “Priority” row.

3.2 Details of Adjustments This section provides adjustment procedures for which explanation in details is necessary. See "3.1 Required Adjustments (p185)" for the adjustments not explained here.
3.2.1 PF Timing Belt Tension Check This section describes PF Timing Belt tension check.
This printer is designed so that the tension of the PF Timing Belt falls within the expected range if you correctly reassemble the unit according to this manual. However, deformation of any related part(s) can cause improper tension of the belt. In such case, replace the Printer Mechanism (Frame Base Assy).
The standard tension range of the PF Timing Belt is as follows: • Standard: 5.0 ± 1.0 N
Tools
Sonic tension gauge
Plastic tweezers
Adjustment procedure When performing the PF Timing Belt tension measurement, make sure of the following.
Perform PF Timing Belt tension measurement before installing the Metal Plate Left.
Bring the microphone of the sonic tension gauge within 5 mm from the PF Timing Belt but do not let it touch the belt.
Flip the PF Timing Belt as weak as the sonic tension gauge can measure it.
Be careful not to damage the PF Timing belt when flipping it with the plastic tweezers.
1. Set the following parameters to the sonic tension gauge:
Weight: Width: Span:
0.96 g/m 2.5 mm 51 mm
2. Bring the microphone of the sonic tension gauge close to the lower center of the PF Timing Belt as shown in Figure 3-1. 3.

Do not touch or press the regulator located under the regulator protection plate of the Ink Leak Measurement Jig.
Adjustment
The Ink Leak Measurement Jig applies pressure by sending air using a syringe into the ink path, and detects the variation of pressure in the ink path between the self-sealing valve in the Printhead and the ink supply holes of the ink cartridges to check the presence of ink leakage. If air leak occurs in the Ink Leak Measurement Jig, the leak check itself cannot be done. Therefore, before performing the leak check, perform the test air leak from the Ink Leak Measurement Jig itself. (The air leak test from Leak Measurement Jig itself is possible by closing the connection port of the Leak Check Adaptor with a finger.)
The ink leak check should be done with the ink tubes secured with the tube clamps and the CR Cover attached after the joint section of the Printhead and the Ink Supply Unit has been secured. (See "Ink Supply Unit (p90)".)

4.1 Overview In this manual, the product name is abbreviated to such as “WF-R5690 series”, however, the last digit of the actual name may differ. Identify your product with the first three digits and refer to the appropriate sections in this manual.
This section provides information to maintain the printer in its optimum condition.
4.1.1 Cleaning Except for the printhead, there are no other mechanical parts or units that require periodic cleaning. However, if need arises, clean the component observing the following instructions.
Instructions for cleaning
Exterior parts such as housing Wipe dirt off with a soft clean cloth moistened with water. For glossy or transparent parts, use of unwoven cloth is recommended to avoid scratching those parts. Inside of the printer Remove paper dust with a vacuum cleaner. Rubber or plastic rollers such as an LD roller/Pickup Roller used to feed paper If paper dust adhered to the rollers decreases the frictional force of the rollers and the rollers cannot properly feed paper, wipe off the paper dust with a soft cloth moistened with diluted alcohol.
Instructions for cleaning ink stains Wipe the stains off with a cloth wrung out of diluted alcohol.
Do not use alcohol for cleaning the transparent parts. Doing so may cause them to get cloudy. When wiping paper dust off the LD roller/Pickup Roller, be careful not to rub against the surface asperity. To minimize the effect on the parts, use diluted alcohol such as 70% diluted ether. After using alcohol for cleaning, make sure to wipe the part off with a soft dry dust-free cloth to remove alcohol traces fully.
4.1.2 Lubrication The type and amount of the grease used to lubricate the printer parts are determined based on the results of the internal evaluations. Therefore, refer to "4.2 Lubrication Points and Instruction (p223)" for the repairing procedures below, and apply the specified type and amount of the grease to the specified part of the printer mechanism.
