It provides a high quality image for most applications. When printing solid ﬁlls, the printhead ejects ink at a 4.25 kHz rate. An image on letter-size paper will take about 2 minutes to print. Phaser 300i and 300RX Color Printer...
Page 95: Premium Mode
Theory of Operation During Enhanced mode printing, the paper is advanced vertically the equivalent of 15 pixels between horizontal passes of the printhead across the paper (every fourth pass is advanced 17 pixels). This minimizes the “banding” that may otherwise appear during Standard mode printing. If there are any blank (white space) raster lines, the drum advances over the white space to the next printable raster line or to the end-of-page.

Page 103: Paper Feeding
Theory of Operation Paper feeding Tray sensors: Tray length and width sensors determine the paper’s size and orientation; whether it is A-size (landscape or portrait), or B-size. Manual-feed sensor: Detects if there is media in the manual-feed slot. If so, the printer uses the paper tray’s size and orientation information (A-size: portrait, or landscape, or B-size) to place the image, unless the printer driver speciﬁes manual feed, this orientation is used.

Page 105: Paper Measure
Theory of Operation Paper measure After clamping the paper, the drum rotates one revolution so that the paper will clear the feed rollers. The print engine also “measures” the length of the paper using its Y-axis paper-edge sensor. The top edge (in the paper clamp) of the paper is positioned in front of the printhead just below the paper tension blade.
Page 106: Printing
Having earlier memorized the length of the media, the drum rotates until the trailing edge of the paper is located above the drum stripper.

Page 107: Fusing And Exiting
Theory of Operation Fusing and exiting The exit motor rotates the ﬁngers of the drum stripper against the drum and moves the fuser rollers into their fusing position. The drum then reverses direction and the paper is stripped off the drum into the fuser rollers. The fuser rollers use tremendous pressure to “cold fuse”...
Page 109: System Power-Up Sequence
Chapter Troubleshooting This chapter discusses troubleshooting the printer. Troubleshooting is discussed with two approaches: A step-by-step veriﬁcation procedure that systematically conﬁrms that particular components of the printer are properly functioning until a problem is found. A symptom/cause scheme that lists particular printer failures and error codes and their possible causes.
Page 110: Print Engine Troubleshooting
Test Pattern Generator can be attached to the printer while the printer is turned on. Select any test pattern using the Test Pattern Generator's ﬁve DIP switches and then press its TEST PRINT button. After the print is made, remove the Test Pattern Generator. Phaser 300i and 300RX Color Printer...
Page 111: Verifying Print Engine Operation By Using Its Self-Test Print
Troubleshooting If the printer prints a test pattern, then the printer's image processor board and print engine are working correctly. The printer's problem resides with the host computer-to-printer connection, or the host computer. Refer to the appropriate topics in Chapter 3 “Verifying the Printer and Host Connections.” (Note that since the Test Pattern Generator prints only through the parallel port, the possibility also exists that the hardware of any of the other hosts interface ports could be non-functioning, and could be the source of the print failure.
Page 112: Verifying Power Supply Operation
The motor and solenoid resistances are listed in Table 6-1, “Motor and solenoid resistances,” on page 6-9. If the power supply operates (with the umbilical cable disconnected), then suspect that the carriage board is overloading the high-voltage supply. Phaser 300i and 300RX Color Printer...
Page 113: Measuring Power Supply Voltages
Troubleshooting Measuring power supply voltages Turn off the printer and unplug it from its power outlet. AC Input: With the VOM set to measure AC voltages, measure for power being supplied to the printer. It should measure between 87 to 128 VAC (115 VAC nominal) or 174 to 250 VAC (220 VAC nominal).
Page 114: Inspecting The Power Supply Fuses
If the power supply is functional, proceed to the procedure “Testing motor resistances” on page 6-9. If the motors and solenoids are functional, but the power supply still does not function, replace it. Refer to the Chapter 8 topic “Power supply” on page 8-27. Phaser 300i and 300RX Color Printer...
Page 115: +40 And Hv Safety Interlocks
Troubleshooting +40 and HV safety interlocks The printer features a mechanical switch safety interlock. The interlock functions off of the rear access cover. When the switch senses the rear cover opened, it signals the power supply to turn off the +40 VDC supplied to the motors, heaters and the high voltage supplied to the printhead.

Page 295 Test Patterns Missing jet. Clogged ink nozzle. A wipe and/or purge should clear this. Typically, for clogged jets, only a single jet will be missing. Multiple missing jets are usually caused by something else as indicated later in this topic. Service Manual...
Page 296 Test Patterns Dirty printhead faceplate. The troubled jet ejects ink but the ink is deﬂected in ﬂight. A printhead wipe should clear this problem. Also ensure that the wiper element is clean and in good working order. Service Manual...
Page 297 Test Patterns Dirty dot clock linear encoder strip. The printhead cannot accurately track its position during its shuttling. The dot clock sensor (mounted on the underside of the carriage board) is being “confused” by the contamination on the dot clock strip. Gently, clean the dot clock strip with water-dampened cloth and then dry the dot clock strip.
Page 298 Test Patterns Dirty paper tension blade. Note the characteristic teardrop-like smearing caused when the paper is pulled past the contamination on the blade. In the test pattern, a dirty paper tension blade may block the upper-most cyan jet and cause a break in the test pattern's long horizontal cyan line. Service Manual...
Page 299 Test Patterns Y-motor malfunction. The gears and belts are not moving smoothly. Note the changes in image density caused by variations in the Y-direction motion of the drum. Service Manual...
Page 300 Test Patterns Bad ground. Typically you will see many missing or intermittent ink-jets of many colors. Check the electrical connections from the printhead to the power supply. Service Manual...
Page 301 Test Patterns Other print defects This illustration shows a combination of print problems. The ink smear problems can be corrected by cleaning ink off of the drum, the paper clamp, or the paper tension blade. Spotting and offsetting can be corrected by replacing the fuser wiper.

Page 308: Test Pattern Generator
The Test Pattern Generator contains PostScript scripts to start test patterns for a number of Tektronix color printers. It allows you to test a printer as if it was receiving a ﬁle from a host computer. The test patterns are generated by the printer's image processor and then printed by the print engine.
