Chapter 3: Operation Theory & Anatomy

The circuit of P231 contain four parts: Main Board, Motors, LED & Sensors and WiFi Module. The

battery is two series(2S) and the capacity is 550 mAH. The voltage of battery is from 8.4V (Battery

full) to 6V (cut off). And the normal voltage of battery for printing is from 8.4V to 7.2V. Main board

transforms the input voltage to TPH necessary voltage (step-up 10.2V +/- 5%) and step-down 5V,

3.3V, 1.8V, 1.0V by voltage converter for ASIC, Memory, and the I/Os. We can use smart phone to

Main Board

 ASIC Architecture

The Quatro 43XX is a highly integrated, fully programmable SOC designed for personal imaging and

printing appliances, i.e. personal-class printers that involve one or more PC-independent functions

such as copy, photo print, print from web, scan to web, fax transmit and fax receive. Specific target

product categories include inkjet multi-function peripherals (MFPs), inkjet direct photo printers, laser

printers, MFPs and internet appliance printers, though the Quatro 43XX is based on Zoran(CSR)’s

QuatroTM platform. This is an advanced SOC architecture that provides original equipment

manufacturers with shorter time-to-market than conventional ASIC solutions through a unique

combination of high performance and easy-to-use programmability.

 TPH Interface

Print data will be shifted into TPH during each clock. After 128 shift clocks, one line data will be

shifted to TPH. Latch/ signal will latch the print data. Strobe/ signal will heat the corresponding

heater elements on TPH according to shift-in data. More the storbe/ time, more the dye of the ribbon

is transferred to paper. P231 using Even-odd Printing method to print color image.

Motors

 Cam motor

Cam motor is a bipolar motor and driven by driver IC DRV8821. DRV8821 is designed to drive dual

bipolar stepping motor and includes pulse-width-modulation (PWM) control of ouput current to 1.5A

MAX. For PWM control, the maximum output current is determined by user's selection of a reference

voltage and sensing resistor.

Chapter 4: Disassembly & Assembly

Safety Instructions

 Read these instructions carefully. Save these instructions for future reference.

 Follow all warnings and instructions marked on the printer.

 Before disassembly, the printer should be power off and remove the battery

pack and adpater. Any PCB that is damage because of mishandling and

disassembly will be judged as “out-of-warranty”.

 Do not place the printer on an unstable cart, stand, or table. The printer may get damaged by

a fall.

 Openings in the chassis and the bottom are provided for ventilation purposes and to ensure

reliable operation of the printer by protecting it form overheating: these openings must not be

blocked or covered.

 Placing the printer on a bed, sofa, rug, or other similar, not firm surfaces may block the

openings. The printer should never be placed near or over a radiator or heat register, proper

ventilation and cooling must be provided at all times.

 The printer should only be operated with the type of power indicated on the marking label. If

you are not sure of the type of power available in your area, consult your dealer or local

power company.

 If an extension cord is used with this product, make sure that the total ampere rating of the

equipment plugged into the extension cord does not exceed the extension cord ampere rating.

Also, make sure that the total rating of all products plugged into the wall outlet does not

exceed the fuse rating.
