To recover from the maintenance error, the dedicated software that can be downloaded
from the web site which can be accessed from STM3 is required.
The printer operation related to the maintenance error recovery is as follows.
• When the waste ink counter reaches the threshold value (1) for the first time and the
maintenance error occurs, the counter threshold of the maintenance error is changed
to threshold value 2 after performing recovery from the maintenance error.
• After the threshold value (2) is enabled, the warning; to notify the possibility of ink
leakage out of the printer, is displayed every time the waste ink counter increases by
1%.
• If the was te ink counter reaches the t hreshold val ue (2), the ma intenance er ror occurs.
Then, the waste ink counter is changed back to the threshold val ue (1) after reco vering
from the maintenance error, and the warning is displayed repeatedly according to the
increment of the waste ink counter until the maintenance error occurs when the
threshold value (2) is reached.
(Recovery from the maintenance error can be performed up to the specified number
of times.)

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.
If the EEPROM data cannot be read out from the old Main Board us ing the Adjustment
Program when replacing the Main Board is required, the Waste Ink Pad Assy must be
replaced with the Main Board at the same time.
After all required adjustments are completed, 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, the adjustment should be made after performing the
initial setting.
In this chapter, the product names are called as follows:
• L550 Series: L550/L551
• L555 Series: L555
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.
• The “Adjustments using the Adjustment Program” need to be performed after
reassembling the printer completely.
If you have removed or replaced multiple parts, make sure to check the required
adjustmen t s for the all parts. And when multiple adjustments must be carried out, be
sure to carry out them in the order given in the “Priority” row.

3.3 Mechanism Adjustment / Check
This section provides the procedure for the mechanism adjustment and check.
3.3.1 Checking the Platen Gap
This section describes the procedure for checking the platen gap (PG).
This printer does not have any PG adjustment mechanism, however, it is designed so that the
platen gap can fall within the expected range if you correctly reassemble the unit (including
using the Epson-specified jigs) according to this manual. If the PG cannot fall within the
standard range after performing the platen gap check described in this section, first check if
the unit is correctly reassembled following the instructions in this manual. Even if the unit is
correctly reassembled but the PG still cannot fall within the standard range, replace the unit
with a new/refurbished one.
The standard range of the PG is as follows:
• Standard: 1.8 ± 0.2 mm
Tools
Thickness gauge: 1.6 mm (x2), 2.0 mm (x2)
Confirmation procedure
Revision A
When checking the PG, make sure of the following.
Check the PG with new ink cartridges inst alled to the CR Unit, and also with all parts
related to the PG installed to the printer (p 57).
Move the CR Unit by pulling the CR Timing Belt.
Be careful not to damage the nozzles of the Printhead with the thickness gauge.

3.3.2 CR/PF Belt Tension Check
This section describes the CR/PF Belt tension check.
This printer is designed so that the each tension of the CR Timing Belt and PF Timing
Belt fall 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 unit with a new/refurbished one.
The standard tension range is as follows:
• CR Timing Belt: 9 ± 1 N
• PF Timing Belt: 5 ± 2.5 N

4.1 Overview
This section provides information to maintain the p rinter in its op timum 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 scrat ching those parts.
Inside of the printer
Remove paper dust with a vacuum cleaner.
Rubber or plastic rollers such as an LD 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.
Revision A
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, 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 Instructions (p72)" for the repairing
procedures below, and apply the specified type and amount of the grease to the specified part of the printer
mechanism.
"4.2 Lubrication Points and Instructions (p72)" also provides information about whether or not the parts which
require lubrication are supplied as ASP and the lubrication st atus when supplied as ASP. For the parts which are
not supplied as ASP, i f t he ir move me nt is not smooth enough, check their lubri cat io n s tat us and lubricate them if
necessary.
