A new model "Tequila (A289)" designed for the Latin American market will be launched in
September 98. Tequila is a slightly modified version of the already existing model "Grand
Kingfisher (Ricoh FT4018/Gestetner 2718z)", especially designed to meet the needs for
the Latin America market.
There will be two destination codes depending on the input voltage: -14 is for 120V areas,
and -24 is for 220V areas. Inch units are the default units for both destination codes.
This RTB clarifies the differences between the base copier and Tequila (based on the style
of the service manual). Also note that the following information is based on the Grand
Kingfisher 120V (inch size) machines.

The paper size actuator for detecting paper size for the upper tray differs from that for the
lower tray. The upper tray has an actuator for the North American market (inch version),
and the lower tray has an actuator for the European market (metric version). The following
shows the available paper sizes for each paper tray.

1. COPIER ACCESSORY CHECK
The following shows the copier accessory list for Tequila. Check the quantity and
condition of the accessories in the box against the following list:
1. Copy tray
2. Safety information sheet
3. Branding kit
A branding kit (A847-00 through -05), which is issued by the sales department, must be
installed on the machine to meet the user’s requirements.. The kit code will depend on the
machine brand, and on which language (Spanish, English, or Portugese) the user
requests. The following lists the accessories for each Tequila branding kit.

SYMPTOM
1. Toner drops onto the copy.
2. Dirty background on copies (Occasional)
3. Image density too high (Occasional)
CAUSE
1. Too much toner is supplied to the development tank due to misdetection by the toner
density sensor.
2. Used toner accumulates in the IU (Imaging Unit), preventing proper recycling.
ACTION REQUIRED
Please follow the procedure as shown below.
1. Remove the IU from the machine.
2. Completely remove the recycled toner in the toner collection coil and the toner recycling
belt area.
3. Install the IU in the machine.
4. Remove the toner bottle from the machine.
5. Make 20, A4 sideways, skyshot copies (solid black copies).
6. Set an original and make some copies to confirm that copy quality is normal.
7. Change the toner supply mode from “0” to “1” using SP30.
8. Make some copies while monitoring the TD sensor output (SP55).
9. Input the value obtained in step 8 in SP53 – TD Sensor Target Control Voltage
Adjustment.
10. Install the toner bottle in the machine.
11. Set an original and make some copies to confirm that copy quality is normal.
Note:
When the developer is replaced, please observe the following for efficient troubleshooting:
1) Do SP66.
2) Do not change the settings of SP30 and SP53. (SP30 must be at “1”. TD
Sensor control voltage must be kept at the same level in SP53, as entered in step
9 above.)

SYMPTOM
1. Toner drops onto the copy.
2. Dirty background on copies (Occasional)
3. Image density too high (Occasional)
CAUSE
Although the toner concentration in the developer is maintained between 3 and 4%,
an increase can be observed when used over an extended period of time. This level
is normally kept under 5% even after 60K copies, however there are rare cases where this
limit is exceeded due to the environmental factors described below. These are thought to
cause the toner to fall onto the surface of the copy.
1. The presence of paper dust as well as conditions such as high humidity are thought to
cause an oversupply of toner to the development unit (by raising the limit of the toner
concentration control to over 6%), which in turn causes the toner to fall onto the copy
surface.

2. In addition, due to this oversupply of toner to the development unit, recycled toner
creates a blockage in the imaging unit and the toner falls from the cleaning area.

ACTION REQUIRED
A. Countermeasure in the field:
Please follow the procedure as shown below if the toner dropping problem occurs in the
field.
1. Remove the IU from the machine.
2. Completely remove the recycled toner at the toner collection coil under the cleaning
blade and the toner recycling belt area. Install the IU in the machine.
3. Remove the toner bottle from the machine. Check that SP38 is 0. (Input "0" if it is not.)
4. Make 20, A4 sideways, skyshot copies (Black solid copies).
5. Set an original and make some copies to confirm that copy quality is normal.
6. Change the toner supply mode from “0” to “1” using SP30.
7. Make some copies while monitoring the TD sensor output (SP55).
8. Input the value obtained in step 7 into SP53 – TD Sensor Target Control Voltage
Adjustment. (If it is more than 127, input 127.)
9 .Install the toner bottle in the machine.
10.Set an original and make some copies to confirm that copy quality is normal.
Note:
When the developer is replaced, please observe the following for efficient troubleshooting:
1) Perform the SP66 to initialize the developer .
2) Do not change the settings of SP30 and SP53. (SP30 must be at “1”. TD Sensor
control voltage must be kept at the same level in SP53, as entered in step 8 above.)
B. Permanent Countermeasure:
This rise in the amount of tone r being supplied will be prevented as de termined by the
copy volume by modifying the software so that an oversupply does not result.
For the
machine of mass production. It is scheduled to be implemented in the
October 1999 mass production.

Model:
If the above symptom should occur in the field before preventative maintenance is
performed, please institute the temporary countermeasure described in the previous
section (A.) and refrain from upgrading the software.
The new software has two major differences from the previous version:
The overall process control and toner density control (maintained by lowering
it to a fixed value every 1K). Due to these differences, it is recommended that
the new firmware be used together with new developer.
NOTE:
Please upgrade the software at the next PM visit (when the developer is replaced).
Please refer to the flow chart on the following page.
(Note: When the developer is replaced, remove the old developer completely. Otherwise
the volume of the developer is increased and it causes the toner to drop.)
