ʻO ka pahu OPC ka pōkole o ka pahu photoconductive organik, kahi mea nui o nā mea paʻi laser a me nā kope. ʻO kēia pahu ke kuleana no ka hoʻoili ʻana i ke kiʻi a i ʻole ke kikokikona ma luna o ka ʻili pepa. Hana ʻia nā pahu OPC me ka hoʻohana ʻana i nā ʻano mea i koho pono ʻia no ko lākou lōʻihi, conductivity uila, a me ka photoconductivity. ʻO ka hoʻomaopopo ʻana i nā mea i hoʻohana ʻia i nā pahu OPC hiki ke hāʻawi i ka ʻike waiwai i ka hana a me ka lōʻihi o kēia mau mea paʻi kumu.
ʻO ka mea mua, ʻo nā pahu OPC kahi mea kumu e hana ai i ka pahu pahu. Hana ʻia kēia substrate me kahi mea māmā a paʻa loa e like me ke alumini a i ʻole ka alloy. ʻO ka alumini kahi koho kaulana ma muli o kāna conductivity thermal maikaʻi loa, e ʻae ai i ka hoʻokuʻu ʻana o ka wela i ka wā paʻi. Pono e ikaika ka substrate e kū i ka wili mau a me ka launa pū me nā mea paʻi ʻē aʻe e hōʻoia i ka maikaʻi o ka paʻi a me ka lōʻihi.
ʻO ka lua o nā mea koʻikoʻi i hoʻohana ʻia i nā pahu OPC ʻo ia ka papa photoconductive organik. Hoʻopili ʻia kēia ʻāpana i ka ʻili o ka substrate drum photosensitive a nona ke kuleana no ka hopu ʻana a me ka mālama ʻana i ka uku electrostatic e pono ai no ka hoʻoili kiʻi. Hoʻohui maʻamau nā papa hoʻoheheʻe kiʻi organik i nā pūhui organik e like me selenium, arsenic, a me tellurium. Loaʻa i kēia mau pūhui nā waiwai photoconductive maikaʻi loa, ʻo ia hoʻi ke alakaʻi lākou i ka uila ke ʻike ʻia i ka mālamalama. Hoʻonohonoho pono ʻia nā papa photoconductive organik e mālama i ke kaulike pololei o ka conductivity, ke kū'ē, a me ke kūpaʻa, ʻo ia ka mea koʻikoʻi no ka hana hou ʻana i nā kiʻi a me nā kikokikona.
No ka pale ʻana i ka ʻāpana photoconductive kūlohelohe, loaʻa i nā pahu OPC kahi pale pale. Hana ʻia kēia uhi me kahi ʻāpana lahilahi o ka plastic a i ʻole resin, e like me ka polycarbonate a i ʻole ka acrylic. Mālama ka pale pale i ka papa organik mai nā mea o waho e hiki ke hoʻohaʻahaʻa i kāna hana, e like me ka lepo, ka uila static, a me ka pōʻino kino. Eia kekahi, pale ka uhi i ka pahu photosensitive mai ka hoʻopili pololei ʻana me ka toner i ka wā e paʻi ana, e kōkua ana i ka pale ʻana i ka toner contamination a me ka hōʻoia ʻana i ka maikaʻi o ke kiʻi.
Ma waho aʻe o ka mea nui i ʻōlelo ʻia ma mua, ua hoʻokomo nā pahu OPC i nā mea ʻē aʻe e hoʻonui ai i kā lākou hana. No ka laʻana, hiki ke hoʻohui ʻia kahi papa pale oxide e pale hou aku i ka papa photoconductive organik mai ka oxygen, ka wai, a me nā mea ʻē aʻe. Hana ʻia kēia papa me kahi kiʻiʻoniʻoni ʻoniʻoni o ka alumini a i ʻole nā mea like a hana ma ke ʻano he pale anti-oxidation. Ma ka hōʻemi ʻana i ka oxidation, hiki ke hoʻonui nui ʻia ka hana holoʻokoʻa a me ke ola lawelawe o ka pahu.
Ua hana ʻia ka hoʻohui ʻana o nā mea i hoʻohana ʻia i nā pahu pahu OPC e hāʻawi i ka maikaʻi o ka paʻi maikaʻi loa, ka lōʻihi, a me ka hilinaʻi. He kumu koʻikoʻi ko kēlā me kēia mea, mai ka substrate e hāʻawi ana i ke ʻano o ka pahu kiʻi kiʻi a i ka papa photoconductive organik e paʻa ana i ka uku paʻa. ʻO ka ʻike i nā mea i hoʻohana ʻia no nā pahu OPC e hiki ai i nā mea hoʻohana paʻi ke hoʻoholo i ka ʻike i ke koho ʻana i nā mea pani, e hōʻoia ana i ka lōʻihi a me ka pono o kā lākou mea paʻi.
I kēia manawa ke hoʻolauna nei au i nā pahu OPC hana kiʻekiʻe noRicoh MPC3003, 4000, a me 6000nā hiʻohiʻona. Loaʻa i ka maikaʻi o ka paʻi a me ka hilinaʻi me kēia mau pahu OPC kiʻekiʻe o ka laina mai Ricoh. Hoʻolālā ʻia lākou no nā hiʻohiʻona MPC3003, 4000, a me 6000. Hanaʻia kēia mau pahu i nā mea ikaika e kū i ka paʻi kiʻekiʻe, e hāʻawi ana i ka hilinaʻi lōʻihi. Hoʻohana ʻo Ricoh OPC roller i ka ʻenehana kiʻekiʻe a me ka hana, hiki ke hāʻawi i kahi hopena paʻi akaka, ʻikea, a pololei. Inā makemake ʻoe e kūʻai i nā pahu OPC, e ʻike i kā mākou pūnaewele (www.copierhonhaitech.com) e koho i ka mea kūpono no kāu kumu hoʻohālike.
I ka hōʻuluʻulu ʻana, he mea koʻikoʻi nā mea i hoʻohana ʻia i nā pahu OPC i ka hana a me ka lōʻihi o nā mea paʻi laser a me nā kope. Hoʻohana pinepine ʻia ka alumini a i ʻole nā alulu e like me ke kumu kumu ma muli o ko lākou ikaika a me ka conductivity thermal. Hoʻokumu ʻia ka papa photoconductive organik me nā pūhui kūlohelohe e like me ka selenium, arsenic, a me tellurium, nāna e paʻa a paʻa i nā uku paʻa. ʻO ka pale pale, i hana pinepine ʻia me ka plastic a i ʻole resin, e pale i ka papa organik maikaʻi mai nā mea o waho a me ka hoʻohaumia ʻana i ka toner. ʻO nā mea hou aku e like me ka pale oxide e hoʻonui i ka hana o ka pahu. Ma ka hoʻomaopopo ʻana i kēia mau mea, hiki i nā mea hoʻohana ke hōʻoia i ka hana maikaʻi loa a me ka lōʻihi o kā lākou mau mea paʻi.
