Three Models
Taurus-C1a (D074)
65 ppm (A4/LT LEF, full color, black-and white)
Memory: 2.5 GB (GW controller), 2 GB (Fiery controller)
HDD: 320 GB (GW controller), 160 GB (Fiery controller)
Taurus-C1b (D075)
75 ppm (A4/LT LEF, full color, black-and white)
Memory: Same as Taurus-C1a
HDD: Same as Taurus-C1a
Taurus-P1 (M044)
75 ppm (A4/LT LEF, full color, black-and white)
Memory: 1.5 GB (GW controller), 2 GB (Fiery controller)
HDD: 320 GB (GW controller), 160 GB (Fiery controller)
Model Names
¾Taurus-C1b: Pro C751EX
¾Taurus-C1a: Pro C651EX
¾Taurus-P1: Pro C751
HDD capacity for the Fiery controller is less than for the AG series (was 500
GB). In the AG series, the HDD was supplied by Ricoh. In the Taurus series, it is
supplied by EFI.
The process speed is the same for all models (352 mm/s). The difference in the
ppm spec is made by a different size of the gap between sheets.

New Fiery Controller
The Color Controller Type E-41a is standard this series. It
is an external type controller with the same design concept
as the QX100 controller for the AG-series.
Standard Fiery
Controller (E-41a) E-41a with
Optional FACI
The E-41a is not compatible with the E-41. Always use the correct controller for
the machine.
The FACI Kit allows the operator to manage jobs more efficiently near the
machine.
¾FACI: Fiery Advanced Controller Interface
The standard controller also has a DVD drive.

Scanning
The machine is equipped with a GW (Ricoh)
scanner and a Fiery scanner as standard
features.
Both scanner features are available even when
GW and Fiery controllers are connected to the
network at the same time.

@Remote
@Remote can acquire only a limited amount of
information via the Fiery controller network port.
For full functionality with @Remote, the system
must be connected via the GW controller network
as well.
This means the machine needs two IP addresses
for full function support with @Remote.

Paper Feed Paths
1. Original Path: ARDF (D074/D075 Only)
2. Paper Bank: Tray 1 (Tandem: 2,000 sheets), Tray 2 (Universal: 500 sheets)
3. Vertical Paper Path

5. Multi Bypass Unit: Tray 6 (500 sheets)
6. Paper Entrance: From LCIT and Multi Bypass Unit (options)
7. Paper Registration Unit: Corrects paper skew and side-to-side registration for
all paper (including paper fed from the LCIT/Multi Bypass Unit)
8. Paper Transfer: Toner image transferred from ITB to paper
9. Transport Belt: Transports paper between paper transfer roller and fusing unit.
Three fans hold the paper in the paper path. Fans (not rollers) are used to hold
the paper in the paper path because the toner is not yet fused.
10. Fusing Unit: Fuses toner image to paper
11. Paper Cooling: Cools paper to reduce curl before it exits or descends to the
duplex paper path
12. Paper Exit: Common paper exit for all paper
13. Inverter/Exit Tray: Paper is fed into this tray, and reverse fed to invert it for
face-down output.
14. Purge Tray: Bottom of the inverter/exit tray. All paper in the paper path of the
main machine is shunted here when a jam occurs downstream.
15. Paper Invert/Switchback: Paper is stopped and reverse fed here to feed it
into the duplex paper path for printing the 2nd side of the sheet.
16. Duplex Paper Path: Transports paper back to the upper horizontal feed path
for paper registration and printing on the second side.

Paper Input
Six possible paper sources.
The paper from each source goes to the paper registration unit.
This unit corrects skew (with a paper buckle adjustment) and side-
to-side registration (with a CIS element and sliding shift roller).
Paper Registration
Unit
Paper is fed from six possible sources:
(1): Tray 1 of the paper bank in the main machine, a tandem tray that holds
2,000 sheets of paper.
(2): Tray 2 of the paper bank in the main machine, a universal tray that holds 500
sheets of paper.
(3) To (5): The optional LCIT has three trays: (3) Tray 3 (1,000 sheets), (4) Tray
4 (2,000 sheets), (5) Tray 5 (1,000 sheets.)
(6): Tray 6, the optional Multi Bypass Tray (500 sheets), is installed on top of the
LCIT.
The paper from each source is sent to the paper registration unit. The registration
unit corrects skew (paper buckle adjustment) and side-to-side registration (with a
CIS element and sliding shift roller).
There is no registration mechanism in the LCIT. All paper registration is
performed in the registration unit of the main machine.
The LCIT has an exit roller lift motor and lift sensor that work together to release
the paper so that it can be free during paper registration in the main machine.
¾See the Paper Registration section of the course for more details.
Due to the shortness of the paper path, solenoids have been added in the paper
path between the paper bank (1st Tray, 2nd Tray) of the main machine and the
paper registration unit. These solenoids retract the transport rollers to free the
paper for paper registration.
¾See the Paper Registration section of the course for more details.
