REFERS TO PRINTHEAD, WHICH I KNOW IS FUNCTIONING OK, BECAUSE I TOOK IT OUT, REPLACED IT, NO ERROR SIGNAL, RAN OFF FIVE VERY VARIED COLOUR PRINTS, EXCELLENT RESULTS. TRIED AGAIN NEXT TIME SWITCHED ON, 5 FLASHES BACK AGAIN. CAN'T STOP FLASHES, PRINTER INOPERATIVE. HOW DO I CIRCUMVENT FLASH SIGNAL WHEN CLEARLY THERE ACTUALLY IS NO ERROR? HOPE YOU HAVE COME ACROSS THIS BEFORE. EVERYTHING WORKS, BUT CANON'S ERROR SET UP PREVENTING USE BY THEIR CUSTOMER. PRINTER OUT OF WARRANTY.

No fuse , PCM/ECM engine computer supplies a five volt reference voltage , a signal wire and a ground .
In modern vehicle design, 5-volt reference signals/circuits are a key aspect of vehicle command and control. As summarized by Gary Goms, the 5-volt reference signal typically "flows through a sensor containing a resistance that varies according to changes in temperature, pressure or position.
DTC P0651: 5-Volt Reference 2 Circuit
You have a bad sensor or a short on the five ref. circuit .
The 5-volt reference 2 buss provides 5 volts to the following sensors:
?€¢
The APP sensor 1
?€¢
The crankshaft position (CKP) sensor
?€¢
The throttle position (TP) sensor 1 and 2
?€¢
The brake booster vacuum sensor
A bad sensor or short on the five volt ref. circuit will bring down the PCM and you will have a no start . I would pull the connectors off each of these sensors listed above to see if five volt ref. comes back to five volts . Well first check five volt ref at easiest sensor to get to . watch this video , he explains better !
The carriage does not accept one or more of the printheads. Typical causes are dirty contacts on the printheads or carriage, defective printhead(s), or a defective carriage.
If parts are replaced or fixed in any of the steps listed below, attempt to verify printer functionality by turning the printer on and printing internal test prints. If functionality is verified, no additional parts should be replaced.
Turn the printer on.
Allow printer to complete initialization.
With the printhead icon highlighted, press ENTER.
Select ReplacePrintheads and press ENTER.
If the message "Printheads still functional" appears, select Yes to continue testing the printheads.
Open the top cover.
Open the carriage cover and remove all of the printheads.
Turn the printer off.
Clean the electrical contacts on the carriage and the printheads using a lint-free cloth dampened with water.
(for this step I suggest using the erraser on the back of a regular pencil instead of a cloth and water)
Allow the contacts to dry.
Reinstall the printheads and close the carriage cover.
Close the top cover.
Turn the printer on and attempt to verify functionality, as instructed in Step 19.
If the error reappears, replace the affected printhead(s).
NOTE: If the printhead error icon is a question mark, each printhead will have to be tested separately, as the printer is not sure which printhead is causing the problem.
Following replacement of the suspect printhead(s), attempt to verify functionality (Step 19).
Regarding your Pixma MP830 printer inquiry (Canon PGI-5 / CLI-8 ink cartridges) and A200 error message, most likely the built-in PRINTHEAD is reaching it's end-of-life and may need to be replaced with a new one. Typically, the average printhead only produces ~4000 to 5000 pages before it electrically fails.
For information on PRINTHEAD failures, please refer to our support page: http://inkjet411.com/?page_id=2934
However, let's run thru the full checklist to screen out additional variables:
Canon A200 Error, Troubleshooting:
Replace ink cartridges if they are empty:
At the risk of stating the obvious (frequently not so obvious in the heat of the moment), find out if the ink cartridges are empty. When in doubt, try a new Canon original ink cartridge to see if this corrects the error.
A data cable of print head is open:
Did you just replace an ink cartridge? Perhaps you shifted a data cable to the print head.
Replace PRINTHEAD if it is damaged. Refer to Canon.com for replacement part.
Turn off the printer for some time
In other troubleshooting tips we have advised any inkjet printer not seeing regular usage to run a test print page. If you are making heavy usage of a Canon inkjet printer, consider giving it a break. This will avoid saturating the printhead with heat, prolonging useful service life.
Update the printer driver:
If you have followed all this with no success, from the printer menu (not computer) push the buttons to get a demo or test page. If everything is ok when you do this, however you get the service error code A200 when you try to produce something productive, odds are good, the print driver the computer is using has gone south (corrupt). When printing on a network, a corrupt printer driver can spread like an unwanted virus. Depending on the network, a driver that has gone rogue may be seen as an updated driver, which network will 'helpfully spread' as an update.
CAUTION: Be advised, the use of compatible/clone cartridges (i.e. sold thru the internet from China) are known to be problematic and may cause printer errors and/or permanent PRINTHEAD failures. We do NOT suggest refilling these types of ink cartridges.....refilling of original/genuine ink cartridges is only suggested!
However, if your printer works routinely after inserting a brand new Canon OEM (original) PGI-5 and CLI-8 ink cartridge(s) in it, this will confirm the cause of failure.
it sounds like ecu is sending wrong signals these new cars are entirely ran off of computers one minor glitch and it screws everything up, but in turn there is million different possibilitys I would take it to oreilys or autozone they offer FREE hookup and will check and see what codes it reading get that information and i could help you alot more miss
Unplug the printer for at least 5 minutes to see if it will clear that error message. The b200 error message is referring to the printhead overheating. It is possible that a printhead nozzle burned out while printing a page and ink ran out. No ink flowing through a nozzle can cause it to overheat and damage it. If waiting for the 5 minute power down doesn't do it, you may have to purchase a new printhead and also check to make sure that you have new ink cartridges.
All
error codes start with the letter "E". An error code of E11 will have
the five indicator lights flash once and the Start indicator light
flash once.
Some
models of Frigidaire washers come with a digital readout display that
informs the operator of the unit's function and any errors.
Error codes
indicate that a problem has occurred and should be addressed. Different
models of Frigidaire washers may vary in their fault displays.
Some
washer models use flashing lights at the unit's start, door lock, wash,
rinse, final spin and control indicators to display error codes.
If
the five indica
tor lights flash more than nine times, this signals a
letter in the error code. The letter "A" stands for 10 flashes, "B" for
11, "C" for 12, "D" for 13, "E" for 14 and "F" for 15 flashes. An error
code of EB2 will have the five indicator lights flash or blink 11
times, and the Start indicator light blink twice
Probably your waste ink counter should be cleaned or replaced before resetting but usually you can get away with resetting once. 1. Start with printer OFF 2. Hold down RESUME and then hold down POWER 3. Release RESUME 4. press RESUME twice, then release POWER 5. let green light blink until printhead has finished moving. 6. Select functions below with RESUME, execute with POWER
0 presses - green light - Test Print (exit service for i960) 1 press - orange light - EEPROM info print 2 presses - green light - EEPROM initialise 3 presses - orange light - reset waste ink counter.
I guess you're getting an error message which is normally one of the below (causes underneath)
Error Code 931
No first HYSNC Signal
Error Code 932
Lost HYSNC =
These errors usually indicate a
failure in the HYSNC signal to the
printhead. Check the continuity of
the cables connected to J3 and J8
on the engine board. If incorrect,
replace the defective cable. The
voltage at J8-4 measures
approximately +5 V dc. If incorrect,
replace the engine board. The
voltage at J3-7 measures
approximately +24 V dc. If incorrect,
replace the engine board. If correct,
replace the printhead assembly.
Error Code 934
Mirror Motor Lost Lock
Error Code 935
Mirror Motor unable to
reach operating speed =
These error codes indicate a
problem with the mirror motor circuit
in the printhead assembly or the
mirror motor cable to the engine
board cable or engine board
assembly. Check the continuity of
the mirror motor cable connected to
J3 on the engine board. If incorrect,
replace the cable. The voltage at
J3-7 measures approximately
+24 V dc. If incorrect, replace the
engine board. If correct, replace the
FRUs in the following order:
engine board
printhead assembly
