@walt2002, hey i was wondering if you were still here, i have read many of your replies and was hoping to hear from you and mownie, you 2 seem to have a wealth of knowledge on these things, i will try the carb first, because it is the easier than the head, but how would the carb cause fire to pop in the carb? im no genius but it seems compression is coming through the carb, and with the few parts in the carb, even no diaphragm, i cant under stand how it would be bad, do they have a ball and spring behind a welch plug like the old model walbro carbs?, i remember years ago when i worked on them a rule of thumb was if you shook them and heard no rattle they were no good, it had something to do with a barometric pressure adjuster valve, you didnt have to adjust the carb in higher locations as you did a b&s carb, just wondering, because i cleaned the carb twice, i put it in a bowl of water while disassembled and used a small straw to blow air through every hole, got bubbles on all, but i will swap them anyway and see, i just want to know what it is, thanks for your advice man

Hard bumps, huh? You might be looking for something mechanically loose like engine mounting bolts or a bad ground or marginal electrical connection. Don't overlook that a wire can fray or break just ahead of a connector and be REALLY hard to spot. Get the battery load tested to make sure it is good. Check BOTH battery cables at both ends and the starter bolts to make sure they are clean and tight. Check the safety interlock switches for proper operation and adjustment. Check the connections at the back of the ignition switch and make sure the fuses have clean and tight connections. Sit down and carefully inspect the tractor from front to back and up to down for anything loose.

The latest high end HP all-in-one printers have fixed ink jets and separate ink cartridges. Both types of HP printers, ink jets on the cartridge and fixed print heads, can be found. Clogging of ink jet heads has always been a big problem and that is why initially, HP started with the print head on the cartridge. It was a patented feature. Later, HP develped a way to keep fixed print heads clear, and then they began to introduce fixed print head printers. Your grainy prints can have two root causes: 1) Poor scan and resultant poor file; 2) Poor printing of a good or bad file. I have an HP flat bed scanner that is going on 10 yrs old and that is the one I rely on when I need to have total control of a scan. it has a rugged mechanism and still produces excellent results. My last two HP all-in-one printers have done excellent work when copying photos. Both of these have fixed print heads. The alignment sensor failed on my first HP all-in-one otherwise I'd still be using it. I can't complain. I had run 11,700 pages through it. I discovered that the ink cartridges were being phased out for this printer (type 02) do I decided to update to a later printer. Glad I did. Although there are fewer cartridges, color prints are just as good and the ink has better smudge resistance.

I have a HP PhotoSmart 3210xi All-In-One and it does all the things you specified above, and does it well. I have run 7000 sheets through it, some were photo paper, and encountered only one jam, and that was because an unnoticed dog eared sheet was in the paper supply. I don't think this model is available any more, but has been superceded by later models with similar capabilities. The major difference for the model that foll0wed this one is choices of connections to the computer. My model included frames for scanning 35 mm transparences, although a dedicated 35 mm scanner probably does a better job due to more pixels per inch. These frames store inside the lid of the printer - very handy. This printer series breaks with HP tradition of ink jets on the bottom of the ink cartridges, thus getting new jets each time a cartridge is changed. The advantage to this is if the ink jets become clogged, these can be tossed away and a new set loaded in. This technology was often limited to one black cartridge plus a 3 color cartridge. This combination was lacking a bit in print detail for photos compared to multi-colors of ink. The PhotSmart series uses fixed ink jets, similar to competitors, and 6 ink colors: Black, Yellow, Light Cyan, Cyan, Light Magenta, and Magenta. With these colors, the printer is able to produce a wide range of colors and shades. The ink is HP's Vivera, a much improved ink. it is fade resistant and supposedly more immune to smearing, however, I find that both printed paper and photo ptints still must be protected from water droplets, and are not smear proof, but are a little more smear proof than hte older ink. The major advantage is much better fade resistance. The ink cost is higher than the older 2 cartridge setup although one only needs to replace individaul colors when used up. Because ofthe fixed ink jet heads, HP has built in an automatic maintence routine to keep the jets clear. Periodically, the printer will enter this routine and purr for about 30 seconds while it runs the jet maintence. During this period, power should not be removed from the printer, and the printer is not available for printing. At first, it is startling when the printer, without waring, suddently makes a noise and enters the maintence routine. After awhile, the user gets accustomed to this noise and the startle factor goes away. Inks are available in single and double packs of individual colors. However, HP does supply a photo kit of inks and about 150 4x6 photo sheets. This kit is rasonable priced for the photo papers, but beware that the ink cartridges contain only enough ink to print the photo papers in the pack assuming average color mix. Some of the cartidges do not contain as much ink as a regular cartridge.
