Regarding your recent inquiry about the HP 45/78 printer error condition (i.e. improper print quality, etc'), it sounds like your cartridge's internal micro-electronics are either clogged or have electrically failed and will need to be replaced. NOTE: The HP 45/78/78+ ink cartridges are extremely robust (compared to many of the newer versions found in market today) and can typically be refilled 8+ times, on average, before suffering a hard internal electronic failure. To verify the electrical health of the ink cartridge, please perform the diagnostic checks below or refer to our HP printer diagnostics document: http://inkjet411.com/?page_id=1813
In some cases the ink cartridges just need to be FIRMLY re-seated into the carriage assembly (also check the cartridge restraining mechanism/arms if present - sometimes these mechanical restraints/arms become loose over time...please double-check these if applicable). We also suggest that you ensure the printer carriage/flex cables (where the cartridge interfaces to the carriage inside the printer) and ink cartridge rear electrical contacts are thoroughly clean to rule out poor connectivity as root cause: http://inkjet411.com/?page_id=1519
Cartridge & Printer maintenance should be evaluated:
Ensure both ink cartridges and flex cable contact surfaces (where the cartridge interfaces to the carriage inside the printer) are thoroughly clean: http://inkjet411.com/?page_id=1519
1) Gently blot the cartridge Nozzle Plate with a damp lint-free towel/wipe - a small amount of ink should be dispensed, and be visible, on the towel (all 3 colors should be present for a Tri-color cartridge).
2) If no ink is dispersed from nozzle plate (i.e. visible on towel) or ink cartridge completely fails to print on paper after installed in printer, then more drastic cartridge and printer cleaning steps will likely need to be performed to recover ink cartridge (NOTE: foam inside cartridge can dry out and become very hard - the foam must be moist with ink to function correctly (i.e. ink flows and wets the nozzle plate). Refer to 'clogged ink cartridge recovery' video here: http://inkjet411.com/?page_id=2818
Providing the ink cartridges are clean, the problem may be caused by a dirty wiper blade or poor seal in the service station (capping station where the ink cartridges park when not in use) and this is causing the poor jetting / print performance issue you are observing. Remove the ink cartridges and thoroughly clean the wipers and seals: http://inkjet411.com/?page_id=1519

NOTE: Unfortunately, alignment pages and internal self test prints will usually print Ok even if the cartridge is internally electrically damaged.
Perform Printer Error Reset:
1. Open the printer/cover as if replacing the cartridge and allow the carriage assembly to move to the cartridges access/loading position.
2. Unplug the power cable from the rear of printer and close the printer's cover.
3. While depressing the power button, plug in the power cable. Keep the power button pressed for about 10-15 seconds, allowing the error flag to reset.
4. After printer powers on, cycle printer power once again and allow printer to fully initialize (may take ~5 minutes for the message/error condition to disappear).
NOTE: If ink cartridge error persists then replace ink cartridge.
*Many cartridges eventually do encounter problems or failures, especially after their original ink is gone and they are re-used, and this is often unrelated to the refill process. Typically the ink cartridge's nozzle plate suffers a break at one of the flexible circuit lines within the base of the cartridge nozzle plate...refer to photo at bottom of this page: http://inkjet411.com/?page_id=509
However, if your printer works routinely after inserting a brand new HP 45 black or HP 78 color ink cartridge in it, this will confirm the root cause of failure.
We trust this detailed technical information provides you some additional insight into the issue you have endured.
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. We do NOT suggest refilling these types of ink cartridges.....refilling of original/genuine ink cartridges is only suggested!
If you need to purchase a new ink cartridge, we suggest you try a remanufactured HP 45/78/78+ ink cartridge from http://www.inkplicity.com/ as their ink cartridges typically have the lowest cost in the USA and reportedly have a high reliability rating (plus free shipping for all orders above $20).

Open the print carriage access door. Check for any packing material that may be blocking the internal components. Check for an orange shipping lock that may still be in place on the left side. Pull the shipping lock out, if present, and discard.
Remove and reinstall the cartridges to make sure they are properly installed. Lift the front center of the print carriage access door to open it. Lift the door up until it locks into an open position. Press down on a print cartridge and allow it to spring back up. Lift the cartridge out of the printer. Do the same for the other cartridge. Slide the black cartridge into the slot on the left and the color cartridge into the slot on the right. Press down on each one to lock it into place. Lower the print carriage access door.
Check the print cartridges to make sure the protective tape has been removed from the ink nozzles. Remove the cartridges from the printer. Remove any tape or labels. Replace the cartridges into the printer.
Push in on the tab on the left side of the clean-out door on the back of the printer to open the door. Lift the door out of the printer. Check for any paper jams. Jammed paper can block the printer cartridge carriage from moving. Pull any jammed paper out.
its the problem of print head in your printer.
You are not the only one facing this problem there are
many other users facing this same problem.in canon printer users out of 10
users ---- 8 users face this problem. Now I will explain the problem In the printer where you insert the cartridges is
called carriage.in the carriage there is a part called PRINT HEAD. In the print
head there are tiny – tiny holes from where the ink passes.when you insert the
cartridge in the carriage /head of the printer the ink from the cartridge
passes from the head.but if the head is got blocked then the ink will not pass
from the head and you get no print out still with the new brand cartridges.now
in the printer there is a in built cleaning assembly , so when you give the
command of cleaning from your pc/laptop the inbuilt cleaning assembly tries to
clean the blocked ink in the tiny holes of the head.but if the ink is got stuck
up hard the cleaning assembly in the printer does not have that much power to
clean the ink in the head.the other procedure to clean the head is a manual
cleaning.in this procedure the head needs to be removed from the printer by
disassembling the printer.but in this case out of 100 only 4 to 5 heads gets
cleaned and start working but that also don’t last long.its not any guarantee
that how much the manually cleaned head will work. In some cases it has been seen that ink gets used only
in cleaning but after inserting new cartridges the printer starts working.if
you have inserted new cartridges in the printer and still don’t get any
printout then its advisable that you go for any other brand printer.hp is the
best brand of printer. Or the other option is you take the printer to local
printer repair shop to get the head manually cleaned if you at present don’t
want to invest in new printer.a repair center have some special tools to clean
the print head its 50 ---- 50 Chance.you can try that first. This will help. Thanks please keep
updated.please do rate the solution positively .thank you for using fixya
you could try cleaning the print heads through the printer utility. Also a little alcohol on a cotton bud to clean the print rollers could help but allow time for it to evaporate and dry before printing.
When using refilled
print cartridges, the Estimated Ink level and the Printer Status Window
may indicate that the print cartridge is out of ink. Either continue to
use the print cartridge until print quality degrades, or replace the
print cartridge with a new HP print cartridge.
The methods of replacing the ink cartridge of the printer follows here:
Open the printer cover
The printer ink carriage will automatically goes to center
Once the carriage is in the center, the printer was ready to replace the ink.
Pull the down slowly the ink tank off the carriage..
Remember the place where the color/black position. Remove each tank one at a time, and replace the ink with a new one.
Close the printer cover and it now ready to printer.

take your ink cartridge out from your printer. you can see at the ink carriage there are little pipes where the ink usually flow from cartridge. If head cleaning and power cleaning does not work, then try to clean those pipes by using 96% alcohol fluids and **** the pipes using something.
You may need a new carriage assembly, with the ink removed, with a mirror you can see down in front where the ink cart. circuit board contacts the carriage. Each slot should have 4 gold wires all of them straight. Bent ones can be straightened carefully, any missing, you'll need a new carriage assembly, a shop repair.
ok the problem is very common.initially remove both the cartridges.then unplug the printer from main outlet and plug back in.this will reset the printer circuit.then after u on the printer bring back the cartridge carriage to cartridge installation position.then first clean the circuit in the carriage that touches and sense your cartridge circuit with a damp cloth.both colour and black carriage circuit.then clean the cartridge circuit too even if its new.then install both the cartridges and close the door and off the printer again and on it after 30 seconds atleast.then check it should work normally.
Have you tried a cleaning cycle? If not, try one. Now run a nozzle check using the status monitor (right click the little printer icon in the bottom right corner of the screen and select nozzle check). Is there any sign of ink on the paper. Try up to three cleaning cycles. If ink is now flowing, but not yet perfectly, don't carry out any more cleaning cycles. Just leave the printer for 24 hours (to allow any air in the print head to disperse). Then repeat the cleaning cycle/wait process. It may take a while to restore a perfect nozzle check print. If these actions produce no positive results, report back.
